Question

write an equation to show how m∠1 and m∠2 are related.

Explanation:

Step1: Identify angle - pair relationship

$\angle1$ and $\angle2$ are supplementary angles (linear - pair of angles).

Step2: Write the angle - sum equation

Supplementary angles add up to 180 degrees. So, $m\angle1 + m\angle2=180$.

Answer:

$m\angle1 + m\angle2 = 180$
