1) Note that in this diagram, we can see a pair of Vertical Angles therefore, we can tell that both are congruent to each other.
2) Having said that, we can write out an equation to find the value of x and then plug it into the expression that corresponds to the measure of angle AFR

Now, the next step is to plug into the x-variable x=13:

Hence, the answer is 124ยบ
