In Fig., if l1 || l2, what is x + y in terms of w and z?A. 180 – w + zB. 180 + w – zC. 180 – w – zD. 180 + w + z

Answer»

Given that,

l₁ ‖ l₂

Let m and n be two transversal cutting them

∠w + ∠x = 180°(Consecutive interior angle)

x = 180° – w (i)

z = y (Alternate angles) (ii)

From (i) and (ii), we get

x + y = 180° – w + z
