Answer:
Complementary
x = 55
Step-by-step explanation:
Complementary angles add up to 90°, while supplementary angles add up to 180°.
In this situation, the two angles add up to 90° (the little box means that an angle is a 90° angle) So, the angles are complementary.
Now, we can write this equation.
x + x - 20 = 90
Simplify.
2x - 20 = 90
2x = 110
x = 55
Just in case, let's check the answer.
Substitute x = 55 into (x + x - 20 = 90)
55 + 55 - 20 = 90
110 - 20 = 90
90 = 90
This is true, so x = 55 is correct.
I hope this helps! Feel free to ask any questions!

Mr. Choe solved the inequality and his work is shown below. 3x+5≤−1 −5 −5 3x≤−6 ÷3 ÷3 x≥−2 Identify and explain Mr. Choe's error.
Answers
Answer:
x ≤ - 2
Step-by-step explanation:
Given the inequality :
3x+5≤−1
Subtract 5 from both sides
3x + 5 - 5 ≤ - 1 - 5
3x ≤ - 6
Divide both sides by 3
3x/3 ≤ - 6/3
x ≤ - 2
Mr.Choe's error was that he changed the inequality sign. The inequality sign in this case does not need to be changed.

Using sampling concepts, it is found that the sample is given by:
C. The 150 businesses who were sent surveys.
What is sampling?It is a common statistics practice, when we want to study something from a population, we find a sample of this population, which is a group containing elements of a population. A sample has to be representative of the population, that is, it has to involve all segments of the population.
In this problem, a group of 150 businesses(sample) is taken from the telephone listings(all the businesses in the listings is the population), hence option C is correct.

A robotics company sells robot vacuum cleaners. Since the newest model was introduced a
while back, the old model has seen its sales fall by a consistent 30% per month. If 8,400 old
vacuum cleaners were sold this month, how many will be sold 3 months from now?
Answers
Steps:
8400*0.7=5880 -> 1 month from now (It’s 0.7 because it decreases by 30% so 70% will remain)
5880*0.7= 4116 -> 2 months from now
4116*0.7= 2881.2 -> 3 months from now
*note that this solution is based on the assumption that the 30% refers to it decreases by 30% of the previous months amount of vacuum cleaners sold, and not the amount of vacuum cleaners sold this month. If it were based on the amount of vacuum cleaners sold this month, the answer would be 840. (8400*0.1)
Ron and Freddy built structures out of snap cubes. Ron's tower had an 8-inch square base. Freddy had a 6-inch square base. If Ron's tower had a volume of 320 cubic inches and Freddy's had a volume of 180 cubic inches, Whose tower was taller? Explain your reasoning.
Answers
Answer: Ron tower's
Step-by-step explanation:
Given
Ron tower has a base of [tex]A_r=8\ in.^2[/tex]
Freddy tower has a base of [tex]A_f=6\ in.^2[/tex]
Suppose the tower is in the shape of a square prism
The volume of Ron and Freddy tower is [tex]320\ \text{and}\ 180\ in.^3[/tex]
The volume of a square-based prism is [tex]V=\frac{1}{3}a^2h[/tex]
[tex]\therefore \text{height of Ron tower is}\ h_r=\dfrac{3V}{A_r}\\\\\Rightarrow h_r=\dfrac{3\times 320}{8}=120\ in.[/tex]
The height of Freddy tower is
[tex]\Rightarrow h_f=\dfrac{3V}{A_f}\\\\\Rightarrow h_f=\dfrac{3\times 180}{6}=90\ in.[/tex]
Thus, the height of Ron's tower is more than Freddy's tower by [tex]30\ in.[/tex]

Answer:
Part A: a) Corresponding angles
Part B: b) 12x - 10 = 10x + 8
Part C: x = 9
m<1 = 98
m<2 = 82
Explanation:
B)
Since they're corresponding angles, they're equal to each other:
12x - 10 = 10x + 8
C)
12x - 10 = 10x + 8
2x = 18
x = 9
m<1:
12(9) - 10 = 98
m<2:
98 + y = 180
y = 82
9514 1404 393
Answer:
A. a
B. b
C. 9, 98, 82
Step-by-step explanation:
See attached.
"Corresponding" angles are those in the same direction from the point of intersection. Here, angles 1 and 3 are both northwest of the intersection point, so are corresponding.
From ...
12x -10 = 10x +8
2x = 18 . . . . . . . . . . . add 10-10x to both sides of the equation
x = 9 . . . . . . . divide by 2
Angles 1 and 3 are the same measure, so we choose the easier expression to evaluate mentally. Multiplying by 10 is easier than by 12, so we use 10·9+8=98 as the measure of angles 1 and 3. Angle 2 is the supplement of this.
