here's a hint...x is in a triangle...therefore the sum of the angles INSIDE the triangle should equal 180
does that help?

all triangles add up to 180 so add the two numbers in the triangle then subtract 180.

@tayla there are two approaches to do the question...one as @lgbasallote and one is that in every such question where exterior angle of triangle is given then use|dw:1349886053172:dw|
