Answer:
167º
Step-by-step explanation:
The interior angles in an n-gon add up to 180(n-2). So, the interior angles in a 28-gon add up to 180(28-2)=180(26)=4680. To find out the measure of one angle divide 4680 by 29. 4680/28 is about 167.
substitute 7 for y then solve for x
x = 2/3
Kyle leaves 1.80 because you have to do 0.15*12
It is y=x-150 because x−150+150=y+150
