Answer 1

Given :-

• line m || QR

What to Find :-

• measure of ∠QPR

Solution :-

Reason :-

• If the transversal line cuts across a parallel line then the interior angles (formed on one side) are supplementary (add to 180°).

So,

∠QPR =180 - (50+45) = 85 degree Ans.

Knowledge Booster :-

• Two angles are called supplementary when their measures add up to 180 degrees.
