Question 103

In the given figure,$QP||RS.$ Find the values of a and b.

Answer 1

Since, $QP||RSandPR$ is transversal.
Therefore, $\angle QPR=\angle SRP\left[alternateinteriorangles\right]\Rightarrow {65}^{\circ }=a\Rightarrow a={65}^{\circ }$

Also, $\angle SRT=\angle PQR\left[correspondingangles\right]\Rightarrow b={70}^{\circ }$
