The value of x is 60, as you wrote. The sum of all angles in a triangle is 180°.

The sum of all angles on a straight line is also 180°. So to find y, solve for the third angle of the triangle on the left.

50 + 60 = 110. 180-110 = 70°.

Now we know 2 of the 3 angles along the line (70° and x, 60°)

70 + 60 + y = 180
130 + y = 180
y = 50

Hope this helps. LMK if you have questions.
