Proving two angles are supplementary

WebbTwo consecutive interior angles are (2x + 10) ° and (x + 5) °. Find measure of the angles. Solution Consecutive interior angles are supplementary. ⇒ (2x + 10) ° + (x + 5) ° = 180° ⇒ 2x + 10 + x + 5 = 180 ⇒ 3x + 15 = 180 Subtract 15 from both sides. ⇒ 3x = 165 Divide both sides by 3. x = 55 Therefore, the consecutive interior angles are: WebbB.
