Question

en la figura a continuación, m∠2 = 55°. hallar m∠1. m∠1 = °

Explanation:

Step1: Identify angle - relationship

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

Step2: Solve for $m\angle1$

$m\angle1=180^{\circ}-m\angle2$.
Substitute $m\angle2 = 55^{\circ}$ into the equation: $m\angle1=180 - 55$.

Answer:

$125$
