Use an algebraic equation to find the measure of the two angles.

• x = 90-16 ; 16°and 74°

• x + x - 16 = 180; 98 °and 82°

• x + x - 16 = 90; 53° and 37°

• x = x -16; 8° and 16°

Use an algebraic equation to find the measures of both angles

• x = 3x - 20; 10° and 10°

• x + 3x - 20 = 90; 27.5° and 62.5°

• x + 3x - 20 = 180; 50° and 130°

• x + 3x - 20 = 180; 150° and 30°
