Question

In the given figure, POQ is a straight line. Find x.
​

Answer 1

Answer:

As POQ is a straight line

POR and ROQ forms linear pair

Therefore POR + ROQ = 180°

(3x + 2 °) + (7x - 12°) =180°

10x - 10 = 180

10x = 190

x = 19

Answer 2

Answer:

X=19

Step-by-step explanation:

Since POQ is a straight line

ANGLE POR+ANGLE QOR=180°

3x+2+7x-12=180°

Solving this,

10x-10=180°

10x=190°

x=19°

And hence the angles are

The ANGLE POR=59

and ANGLE QOR=131
