Question

Use this diagram and information given to find mangleAFE.

Answer 1

Since they are collinear, it means the BFD is a straight line and all the angles formed by the lines resting on a straight line add up to $180$ degrees. So, $65 + 65 + x = 180$

When we add $65$ and $65$ we get $130$. So,

$130 + x = 180\\\\x = 180 - 130 = 50$

Henceforth, $x$ or angle $AFE$ is equal to $50$ degrees. :D
