Answer:

First you need to find x

by doing this you know that a triangle is 180 degrees

then you would add 33+87=120

x=180-120

180-120=60

we know that is is a straight line which is 180 degrees

so then you would go 180-60=120

So y would be 120

Answer:

The answer to your question is 120°

Step-by-step explanation:

1.- The internal angles in a triangle equals 180°

           33° + 87° + x = 180               Substitution

           x = 180 - 33 - 87                   Simplification

           x = 60°

2.- The sum of supplementary angles equals 180°

          x + y = 180

          60 + y = 180                          Substitution

          y = 180 - 60                           Simplification

          y = 120°
