Answer:

see explanation

Explanation:

The exterior angles of a polygon , sum to 360°

sum the 5 angles, equate to 360 and solve for x

2x + 2x + 5 + 3x + 10 + 3x - 15 + x + 30 = 360 ( simplify left side )

11x + 30 = 360 ( subtract 30 from both sides )

11x = 330 ( divide both sides by 11 )

x = 30

The measures of the exterior angles are

2x = 2 × 30 = 60°

2x + 5 = 2(30) + 5 = 60 + 5 = 65°

3x + 10 = 3(30) + 10 = 90 + 10 = 100°

3x - 15 = 3(30) - 15 = 90 - 15 = 75°

x + 30 = 30 + 30 = 60°
