Question

17In the given Fig: PQR is a straight line. If ∠SQR = 80°,
find ∠PQS​

Answer 1

Step-by-step explanation:

∠PQS + ∠SQR = 180° (Linear pair of angle)

> ∠PQS + 80° = 180°

> ∠PQS = 180° - 80° = 100°

Answer 2

Answer:

We are given the following in the question:

PQR is a straight line.

$\sf{\angle SQR = 75^\circ}$

We have to find the measure of angle ∠PQS.

Since, PQR is a straight line, we have,

$\sf{ \angle PQS + \angle SQR = 180\\\angle PQS + 75 = 180\\\angle PQS = 180 - 75\\\angle PQS = 105^\circ }$

Thus, the measure of angle PQS is 105 degrees.
