Answer: 28.8°
<u>Step-by-step explanation:</u>
∠A = 5(∠B) + 7.2°
∠B = ∠B
Since they are on a straight line, they form a linear pair (sum = 180°)
∠A + ∠B = 180°
Use Substitution:
5(∠B) + 7.2° + ∠B = 180°
Add like terms:
6(∠B) + 7.2° = 180°
Subtract 7.2° from both sides:
6(∠B) = 172.8°
Divide both sides by 6:
∠B = 28.8°
1.
a. -10/7
b. 5/3
c. 3.02
d. 6 1/2 (it is a bit blury, hard to tell)
explanation- so the opposite of a positive is a negative, the opposite of a negative is a positive. so it is the same for this. for example 10/7 is positive so you make it a negative for it be the opposite.
i would help with the rest, but it is hard when you have to label things on a diagram when you are doing it on a computer like this. sorry!

Answer:
3/2
Step-by-step explanation:
Answer
x=10
Step by step explanation:
It is a dilation to you would divide the known sides with each other.
8/2=4
16/4=4
So, you would then multiply 2.5 by 4 which would get you 10
preetty sure this is it, if its wrong then im sorry
