Question

I know this answer is 65° but how explain​

Answer 1

Answer:

So see, a straight line means 180 degree

That'll therefore mean

110 + PQR = 180

So we subtract 110 from 180 and get 65

Hope this helps! ty

Answer 2

PQR = 65 (LINEAR PAIR)

A linear pair is a pair of adjacent angles formed when two lines intersect.

A straight line is 180°

So when we subtract 110 from 180 we'll get the other angle that is 65°

Hope it helps ☺️
