Question

Ac df and yz are straight lines and all angles are in degrees. by first considering the angles on line abc, show that ac is parallel to df. ​

Answer 1

Step-by-step explanation:

Angle ABY = Angle YBC

(X+25) +(2x+50) = 180

3x + 75 = 180

3x =180 - 75

X = 105/3

X = 35

Angle YBC = 2×35 + 50 = 120

Angle BEF = 5×35 - 55 = 120

Angle YBC = Angle BEF

AC // DF
