Answer:

65° , 73° , 90° , 132°

Explanation:

the sum of the exterior angles of a polygon is 360°

sum the 4 angles, equate to 360 and solve for x

x + 132 + x + 8 + 90 = 360 ( simplify left side )

2x + 230 = 360 ( subtract 230 from both sides )

2x = 130 ( divide both sides by 2 )

x = 65

x + 8 = 65 + 8 = 73

the 4 exterior angles are 65° , 73° , 90° , 132°
