Question
Solve each $\triangle L M N$ described below. Round measures to the nearest tenth.$$m \angle M=46, m \angle L=55, n=16$$
Step 1
We know that the sum of the angles in a triangle is 180 degrees. So, we subtract the measures of $\angle M$ and $\angle L$ from 180. $$m \angle N = 180 - m \angle M - m \angle L = 180 - 46 - 55 = 79.$$ Show more…
