Answer:
Step-by-step explanation:
mZMNT = :Given the 35 degree in 25 degree angle, we can complete this triangle on the far right by subtracting from 181 80 -35 -25. It means this one has to be 120°. And then our ultimate goal is to find the measure of angle m n. T, Which is this one here. And if we've got isosceles triangle in the center here, these exterior angles are going to be congruent, so this must be 120° as well.
