Need help plzzz???!?????!

Answer:

137

Step-by-step explanation:

First start with what you know. The measure of the interior angles of a triangle total to $180^{o}$ so 51 + 2x + x = 180, then 51 + 3x = 180, 3x = 129, so

x = 43, the exterior angle is on a straight line with x so

x + exterior angle = 180 [since they are supplementary], since x = 43 then

43 + e = 180, so e has to be 137
