A:
Step-by-step explanation:Supplementary angles equal 180°1. Let the two angles be x and ythen y = 4x + 10x + y = 180x + (4x + 10) = 1805x + 10 = 1805x = 180 - 105x = 170x = 170 / 5x = 34x = 34y = 1462. if the two angles are equal then divide 180 by 2 to get 903. 180 - x = 3(90 - x)180 - x = 270 - 3x2x = 90x = 454. 180 - x = 2x - 12180 - 12 = 2x + x168 = 3xx = 56
