Answer:
120
Step-by-step explanation:
1. Find the value of x.
The angles in a triangle have a sum of 180 degrees. To find x, add up the other two inside angles and subtract the sum from 180.
87 + 33 = 120
180 - 120 = 60 degrees.
x = 60
2. Angle y is supplementary to angle x, meaning that the sum of the two angles equals 180.
180 - 60 = 120
y = 120
