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
