Answer:
The measure of angle MNL is 
Step-by-step explanation:
see the attached figure to better understand the problem
In this problem we know that
angle GNH is congruent to angle KNL
-----> by vertical angles

so

Find the measure of angle MNL
------> by complementary angles
Substitute and solve for m<MNL
