it would be 50 degrees, because it is a vertical angle with the one below it, which is 50 degrees. i was taught that vertical angles are congruent

The two triangles are the same.

Find the third angle of the triangle on the bottom.

All 3 angles of a triangle add up to 180.

65 + 65 = 130

Now subtract it from 180:

180 - 130 = 50

So 'x' is equal to 50 degrees.
