Answer:
144 degrees
Step-by-step explanation:
1 exterior angle = 360/number os side
= 360/10 = 36
interior angle = 180 - 36
= 144
Answer:
The first blue option <em>or </em> 8x - 17 = 5x + 19
Step-by-step explanation:
They are vertical angles, so they will be set equal to each other.
Have a nice day!
I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly. (ノ^∇^)

First, Substitute x + y = 160 into equation
x = 160 - y

Substitute that into

The answer is 110.
