Answer:

y = 120

Step-by-step explanation:

Interior angles of a triangle add up to 180°

So,

x+87+33 = 180

x + 120 = 180

Subtracting 120 to both sides

x = 180-120

x = 60°

Now

Angles on a straight line also add up to 180°

So,

x+y = 180

60 + y = 180

Subtracting 60 to both sides , we get

y = 180-60

y = 120

ANSWER:
33+87+x=180(angle sum property)
120+x=180
x=180-120
x=60
If x =60 then ,
X+Y=180(linear pair)
60+Y=180
Y=180-60
Y=120
