Answer:

x = 30

y = 30

Step-by-step explanation:

The marked triangle is an equilateral triangle.

The top angle is marked as a right angle.

x + 60 = 90            Subtract 60

x = 90 - 60

x =30

The unmarked interior angle of the triangle that contains x and y is the supplement of a 60 degree angle

60 + unmarked angle = 180

unmarked angle = 180 - 60

unmarked angle = 120

unmarked angle + x + y = 180

120 + 30 + y = 180

150 + y = 180                 Subtract 150 from both sides.

y = 180 - 150

y = 30
