Answer» let angles be a b and ca+b + c = 180 # sum of angles of triangleWe are givena - b = 20 , thus a = b + 20b - c = 56 thus b = c + 56a = b + 20 = c + 56 + 20 = c + 76a + b + c = 180(c + 76) + (c + 56) + c = 1803c + 132 = 1803c = 180 - 132 = 48 c = 16b = c + 56 = 16 + 56 = 72a = c + 76 = 16 + 76 = 92 |
