Answer:
x=40
Step-by-step explanation:
7(2x-5)-11=3(5x-2)-2x Distribute
14x-35-11=15x-6-2x Simplify
14x-46=13x-6 subtract 13x and add 46
x=40
Exterior angles always add up to 360 degrees so for 30-gon each exterior angles is 12 degrees (360/30)
To get the interior angles you subtract 180 from 12 to get 168 degrees
