3. Two lines PQ and RS intersect at O. If anglePOR = 50', then value of angle
ROQ is
(a) 120° (b) 130° C) 90° (d) 150°​

Answer 1

Answer:

If we took POQ=180 because linear pair

So angle POR+angleROQ=180

SO,

50+X=180

X=180-50

X=130

option B

Answer 2

The value of $\angle ROQ$ is 130°

option (b)

Step-by-step explanation:

Two lines PQ and RS intersect at O

given : $\angle POR = 50^\circ$

we have to find the $\angle ROQ$

from the figure ,

$\angle POR + \angle ROQ = 180^\circ$ (linear pair )

therefore

$50^\circ + \angle ROQ = 180^\circ \\\\\angle ROQ = 180-50 \\\\\angle ROQ = 130^\circ$

hence , The value of $\angle ROQ$ is 130°

option (b)
