Question

write an equation to show how m∠1 and m∠2 are related.
m∠1 + m∠2 = 180°
when the measures of two angles sum to 180° they are supplementary. ∠1 and ∠2 are supplementary angles.
m∠1 = 137°. find m∠2.
m∠2 = \square°

Explanation:

Step1: Use supplementary angle equation

Given $m\angle1 + m\angle2 = 180^\circ$

Step2: Substitute $m\angle1 = 137^\circ$

$137^\circ + m\angle2 = 180^\circ$

Step3: Solve for $m\angle2$

$m\angle2 = 180^\circ - 137^\circ = 43^\circ$

Answer:

43
