Question

Given, ∠ POR = 4x and ∠ QOR = 2x- 60. If POQ is a straight line, then value of ∠ QOR is

Answer 1

Answer:

Step-by-step explanation:

Given that <POR= 4x

<QOR=2x-60°

As POQ is a straight line,

So <POR+ <QOR=180° (linear pair)

So 4x+2x-60°=180°

=> 6x-60°=180°

=> 6x=180°+60°

=> 6x=240°

=> x=240°/6

=> x=40°.

Thus, the value of x is 40°.
