Question

In the figure, a∥e , m∥n , and m∠1= 108°. What is the m∠3?

Answer 1

I assume you meant N1=108 since there is no M1 in the pic
N1=N2 and N2 =M3 (since M and N are parallel)
which means M3 = 108<span />

Answer 2

Answer:

m∠3=$108\°$

Step-by-step explanation:

we know that

If n is parallel to m

then

m∠3=m∠1 ------> by alternate exterior angles

so

m∠3=$108\°$
