Answer: y = 140, x = 159 Step-by-step explanation: Angle y: we can find this angle by subtracting 40 from 180, 180-40 = 140 = y Angle x: Some measure of an angle plus angle b is equal to 180 degrees: 180-61 = 119 We can now find the measure of the third angle of the triangle: 180-(119+40) = 21 The third angle plus angle x is equal to 180: 180-21 = 159 = x
