Question

in the figure below, m∠1 = 37°. find m∠2.

Explanation:

Step1: Recall angle - sum property

$\angle1$ and $\angle2$ are supplementary angles, so $\angle1+\angle2 = 180^{\circ}$.

Step2: Solve for $\angle2$

$\angle2=180^{\circ}-\angle1$. Given $\angle1 = 37^{\circ}$, then $\angle2=180 - 37$.

Answer:

$143^{\circ}$
