Question

solve for m∠pqr. answer attempt 1 out of 2 m∠pqr =

Explanation:

Step1: Identify angle - addition principle

The measure of $\angle PQR$ is the sum of the two adjacent angles $\angle PQS$ and $\angle SQR$.

Step2: Add the angle measures

$m\angle PQR=m\angle PQS + m\angle SQR$. Given $m\angle PQS = 72^{\circ}$ and $m\angle SQR=87^{\circ}$, then $m\angle PQR=72^{\circ}+ 87^{\circ}$.
$m\angle PQR = 159^{\circ}$

Answer:

$159$
