45 Degrees, all angles of a triangle add up to 180.

A: It would be 35 degrees. :) E: Since all triangles equal 180 degrees you already have 2/3 of the whole triangle. So you would add them together (Angles D & E) 120+25=145. Now to find x you’re going to have to subtract 180 by 145 and you get 35 degrees.
