Answer:
62°
Step-by-step explanation:
Given that the triangle has two angle measures of 41° and 77°.
All the angles in a triangle must add up to 180° (e.g. 20° + 60° + 100°). So we write a simple equation to solve for the mystery angle measure:
Let x = the missing measure

Now that we have our equation, let's start solving it. First, we need to add 41 and 77 together which simplifies the equation: 
Then we subtract 118 from both sides to isolate x - this will give us the value of this variable: 
Therefore, the third angle must have a measure of 62°.
I believe that it is E since it is pretty obvious where the middle is you just do rise/run which gives you 2,-1
