Question

in the figure below, m∠1 = 38°. find m∠2. m∠2 = °

Explanation:

Step1: Identify angle - relationship

$\angle1$ and $\angle2$ are supplementary angles.

Step2: Use supplementary - angle property

Supplementary angles add up to $180^{\circ}$, so $m\angle2=180^{\circ}-m\angle1$.

Step3: Substitute the value of $m\angle1$

$m\angle2 = 180 - 38$.
$m\angle2=142^{\circ}$

Answer:

$142$
