Supplementary Angles

The measure of angle a = x + 16. The measure of angle b = 4x - 5. Find x.

• x = 10

• x = 7

• x = 8

• x + 16 = 4x - 5

Find the measure of the supplementary angles.

• obtuse angle = 125, acute angle = 55

• obtuse angle = 120, acute angle = 60

• obtuse angle = 110, acute angle = 70

Which equation could be used to solve for x?

• 4x + 5 + x - 3 + 3x + 2 = 90

• 4x + 5 + x - 3 + 3x + 2 = 180

Find y.

• 11y - 36 = 63

• y = 11

• y = 9

• y = 10
