Question

if ∠1 and ∠2 are supplementary angles and m∠1 = 76 degrees, then the m∠2 = type your answer degrees. fill in the blank 4 points

Explanation:

Step1: Recall supplementary - angle definition

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

Step2: Solve for $m\angle2$

Given $m\angle1 = 76^{\circ}$, then $m\angle2=180 - m\angle1$. Substitute $m\angle1 = 76^{\circ}$ into the equation: $m\angle2=180 - 76$.
