Question

how are ∠1 and ∠2 related? complete the equation. m∠1 + m∠2 = \boxed{}^\circ an error has occurred. please enter a number. (figure shows three intersecting lines with a right angle at the intersection of g and h, forming ∠1 and ∠2)

Explanation:

Step1: Identify right angle

Line $g$ is perpendicular to line $h$, so $\angle 1 + \angle 2$ forms a right angle. A right angle measures $90^\circ$.

Step2: Set up the equation

$m\angle 1 + m\angle 2 = 90$

Answer:

$90$
