A right triangle has an angle that measures 32 degrees. What is the value of the other angle?
Answer:
58
Step-by-step explanation:
right triangle is usually 45°45°90°
given angles: 90°and 32°
90+32=122
then 180-122=58°
Taking the sum of the three interior angles of a triangle and the definition of a right triangle, you get that the value of the other angle is 58°.
The right triangle is a geometric figure that is considered as a polygon formed by three sides that form a right angle and two acute angles. That is, a right triangle is one that has an interior angle that is right, that is, it measures 90º.
On the other hand, the sum of the three interior angles of a triangle is equal to 180 °. Being α, β and γ the interior angles of the triangle, then:
α + β + γ= 180°
Being a right angle, whose value is 90 °, and another angle whose value is 32 °, it is replaced:
90° + 32° + γ= 180°
and solving you get:
122° + γ=180°
γ= 180° - 122°
γ= 58°
Then, the value of the other angle is 58°.

An isosceles triangle’s altitude will bisect its base. Which expression could be used to find the area of the isosceles triangle above?
Answer:
[tex]\dfrac{\sqrt{40}\cdot \sqrt{40}}{2}[/tex]
Step-by-step explanation:
The length of the base is the distance between the points 4+2i and 10+4i, so
[tex]\text{Base}=|10+4i-(4+2i)|=|10+4i-4-2i|=|6+2i|=\sqrt{6^2+2^2}=\\ \\=\sqrt{36+4}=\sqrt{40}[/tex]
The middle point of the base is placed at point
[tex]\dfrac{4+2i+10+4i}{2}=\dfrac{6i+14}{2}=7+3i[/tex]
The length of the height is the distance between the points 5+9i and 7+3i
[tex]\text{Height}=|5+9i-(7+3i)|=|5+9i-7-3i|=|-2+6i|=\sqrt{(-2)^2+6^2}=\\ \\=\sqrt{4+36}=\sqrt{40}[/tex]
So, the area of the triangle is
[tex]A=\dfrac{1}{2}\cdot \text{Base}\cdot \text{Height}=\dfrac{\sqrt{40}\cdot \sqrt{40}}{2}[/tex]

Richard’s store sells pineapples and grapefruits. Pineapples originally cost $5.15 apiece, and grapefruits originally cost $2.25 apiece. Richard reduced the prices to $3.88 for a pineapple and $1.56 for a grapefruit. Which fruit had its price reduced by a greater percent, and how many percentage points greater was that reduction than the other? Round to two decimal places. (Express your answer in percentage points; for example, 15% is 3 percentage points greater than 12%.) a. The price of pineapples experienced a reduction 5.99 percentage points greater than the price of grapefruits. b. The price of pineapples experienced a reduction 19.90 percentage points greater than the price of grapefruits. c. The price of grapefruits experienced a reduction 6.01 percentage points greater than the price of pineapples. d. The price of grapefruits experienced a reduction 11.50 percentage points greater than the price of pineapples.
Answer:
c. The price of grapefruits experienced a reduction 6.01 percentage points greater than the price of pineapples.
Step-by-step explanation:
The original price of Pineapples=$5.15
New price of Pineapples=$3.88
Find change in price of Pineapples
Change in price=original price- new price
[tex]=5.15-3.88=1.27[/tex]
The price of Pineapple was reduced by $1.27
% reduction in price
(reduction value/original value) × 100
[tex]=\frac{1.27}{5.15} *100=24.66[/tex]
=24.66%
The original price of grape fruits=$2.25
New price of grape fruits=$1.56
Change in price of grape fruit
Change in price= original price -new price
[tex]=2.25-1.56=0.69[/tex]
% reduction in price of grape fruits
(reduction value/original value)×100
[tex]=\frac{0.69}{2.25} *100=30.67[/tex]

Solve this equation for x. Round your answer
to the nearest hundredth.
1 = In(x + 8)
Answer:
e -8 =x
Step-by-step explanation:
1 = In(x + 8)
To get rid of the natural log, raise each side to the base e
e^1 = e^ (ln(x+8))
e^ln cancels
e^1 = x+8
Subtract 8 from each side
e^1 -8 = x+8-8
e -8 =x
Answer this question thanks
First subtract 17 to both sides (what you do on one side you must do to the other). Since 17 is being added, subtraction (the opposite of addition) will cancel it out (make it zero) from the left side and bring it over to the right side.
p + 17 - 17 < 19 - 17
p + 0 < 2
p < 2
For the graph will you have a empty or colored in circle?
If the symbol is ≥ or ≤ then the circle will be colored in. This represents that the number the circle is on is included.
If the symbol is > or < then the circle will be empty. This represents that the number the circle is on is NOT included.
Which direction will the ray go?
If the variable is LESS then the number then the arrow will go to the left of the circle.
If the variable is MORE then the number then the arrow will go to the right of the circle.
In this case your inequality is:
p < 2
aka p is less then two
This means that the graph will have an empty circle and the arrow will go to the left of 2. (image below)

Answer:
5
Step-by-step explanation:
hihi, so the key to this is manipulating the equations. Realizing that 7a + 7b is just 7*(a+b) makes this fairly simple since you already know what a+b equals and just have to multiply that by 7. Same goes with x, y, and z. 6x + 6y + 6z is the same as 6(x + y + z). Thus, -1 * 7 + 2 * 6 = 5

12, 15, 18, 21, 24, 27, 30, 33, 36, 39, 42, 45
1 2 3 4 5 6 7 8 9 10 11 12
45 is the 12th term
Answer:
Option b - 45
Step-by-step explanation:
Given : Sequence 12,15,18,21,...
To find : What is the 12th term in the sequence?
Solution :
Sequence 12,15,18,21,... is an arithmetic progression.
Where, first term is a=12
Common difference is d=15-12=3
The nth term of the sequence is
[tex]a_n=a+(n-1)d[/tex]
The 12th term is
[tex]a_{12}=12+(12-1)(3)[/tex]
[tex]a_{12}=12+(11)(3)[/tex]
[tex]a_{12}=12+33[/tex]
[tex]a_{12}=45[/tex]
Therefore, The 12th term of the sequence is 45.
So, Option b is correct.
Which property of exponents must you apply to the expression p^1/2 to derive p as the result?
We apply the following property:
(x^n)^m = x^(n • m)
Let m = 2
(P^1/2)^2 = P^(1/2 • 2) = P
Follow below steps;
The property of exponents that you must apply to the expression p1/2 to derive p as the result is the power law for fractional exponents. This law states that when raising a number to a fractional exponent, it is equivalent to taking its root.
Example: p1/2 is the same as taking the square root of p, resulting in p.
When dealing with fractional exponents like 1/2, remember that they represent roots, such as square roots in this case.

Answer:
Area of circle R = 75π un² or ≈235.5 un²
Step-by-step explanation:
The problem says that m∠TRS = 120º. The total number of degrees in a circle is 360º. 120º is a third of 360º. Therefore, we can prove that the shaded sector is a third of the circle.
The problem then says that the area of the shaded sector is 25π and we have to calculate the area of the entire circle. Since we already know that the shaded sector is a third of the circle, we can simply multiply 25π by 3 in order to calculate the area of t he entire circle.
25π × 3 = 75π.
Area of circle R = 75π un² or ≈235.5 un²
Answer: 75
Step-by-step explanation:
If the measure of TRS is 120, that is 1/3 the total of 360. Meaning the area of the shaded part is 1/3 the area of the full circle. If the area of the shaded part is 25, that means 25 is 1/3 the full area. the equation for that can be (25 = 1/3x) with x being the full area of the circle.
To solve just multiply both sides by the reciprocal of 1/3, which is 3.
25 x 3 = 75, which is your answer.

Step-by-step explanation:
The question states that the car depreciates every month over the 2 years. This means that the value will go down from its original price. So with that we can rule out the last two choices which has addition.
The depreciation is every month, so in 2 years, there are 24 months. We can get the total deduction by multiplying the depreciation amount and the number of months that had passed over 2 years.
