PLEASE HELP!!!!!

the figure shows a triangle with unknown angles.

which equation shows the relationship between the exterior angle and the interior angles?

A) m∠2=m∠1+m∠4
B) m∠2=m∠3+m∠4
C) m∠4=m∠1+m∠2
D) m∠4=m∠2+m∠3

PLEASE LOOK AT PICTURE!!!!!!

Answer 1

option 3

Explanation:

In a triangle, the angle that is supplementary to one angle is equal to the other two angles' degrees added together.

In this case, angle 4 is supplementary to angle 3, which means that angle 4 is equal to angle 1 + angle 2. We can see that this is the third option.
