Angle Equations Math

Set up the equation to find the missing angle

• 40 + 90 = x

• 40 + 90 + x = 180

• 180 = 40 - 90

• x + 40 + 40 = 180

Two lines are parallel and cut by a transversal such that angle 1 and angle 8 are alternate exterior angles. What is the measure of angle 8 when the measure of angle 1 is 120°?

Two lines are parallel and cut by a transversal such that angle 1 and angle 8 are consecutive exterior angles. What is the measure of angle 8 when the measure of angle 1 is 120°?

Which equation would you use to find the measurement of the third angle of this triangle?

• 36 + 57 + a = 360

• (36 + 57) - a = 180

• 36 + 57 + a = 180
