Question

Solve this equation
​

Answer 1

Answer:

If l and m are parellel,

z + 105 = 180 ------------------ Sum of Co-Interior Angles = 180

z = 180 - 105

z = 75

40 + z + y = 180 ---- Sum of angles on a straight angle = 180

40 + 75 + y = 180

115 + y = 180

y = 180 - 115

y = 65

x = 40 ---- Alternate Interior Angles are Equal

Therefore, x = 40, y = 65, z = 75.
