Question

1. In the fig, PQ || RS and QR || ST. If the angle between PQ
and QR is 39°, find the value of x and y.
R
W
39
V
0​

Answer 1

Since PQ||RS and QR is transversal,

so x = 39 (alternate interior angle)

Again QR||ST and RS is a transversal.

Therefore, y = x [Alternate interior angles]

or y = 39
