Question

pq is ║ to rs find x nd y.

Answer 1

Answer:

x=55°, y=40°

Step-by-step explanation:

First make a line mn through O parallel to PQ.

By corresponding angles, find the value of x=55°.

Let the line of transversal be AB. In triangle ABO,

angle OBA+65+30=180. (Linear angle)

therefore angle ABO = 85°.

In triangle ABO,

x+y+85=180°. (Interior angle property)

=55+85+y=180

=y = 180-55-85

or y=40°
