Answer:
so the labelled angles are 30 and 90, but it only shows one 90. In fact there are 4 angles of 90. The marked 90 then the vertical angle and the complementary angles. All triangles equal 180 so the given 30 and 90 are taken from the 180.
180 -30-90= 60
But y is the opposite of the 30 which makes y=30
so that leaves x = 60
y=30 and x=60
