Question

In the triangle below, what is the length of MN

Answer 1

A because look at ML it is 20

Answer 2

A. 20

Explanation:

The MNL triangle is isosceles, because it has two equal angles

MLN = 50 = MNL

Then, as it is an isosceles triangle, ML = MN. We already know that ML = 20, thus MN has to measure the same. We conclude MN = 20.
