Answer:
x = 72.5°
Step-by-step explanation:
x = 1/2(80 + 65)
x = 145/2
x = 72.5
Answer:

The solution for
is all real numbers less that or equal to 36.
Step-by-step explanation:
Given expression:

To find the solution for 
Solution:
In order to solve for
, we will make sure to isolate the unknown variable
on left side alone by doing math operations on both sides of the inequality.
We have:

Multiplying both sides by 2.

The 2 on left side will cancel each other leaving
alone.
Thus, we have:

Thus, solution for
is all real numbers less that or equal to 36.
