Question

In the adjacent figure , find x​

Answer 1

Answer:

$according \: to \: exterior \: angle \: property \: \\ x + x = 140 \\ 2x = 140 \\ x = \frac{140}{2} \\ x = 70 \\ \\ if \: you \: need \: to \: find \: y \\ y + 140 = 180 \\ y = 180 - 140 \\ y = 40 \\ \\ \\ hope \: the \: answers \: are \: correct..$

Answer 2

Answer:

Exterior angle is equal to the sum of opposite to interior angle

So ∠PQR+∠QPR =140°

=> x + x = 140°

=>2x = 140°

=>x =$\frac{140}{2}$

=>x = 70°

Hope this answer helps you out.
