Find angle sum therom

y = 120°

Step-by-step explanation:

angles in a triangle add up to 180 degrees

180 - (87 +33) = 60

x = 60 degrees

angles on a straight line add up to 180 degrees

180 - 60 = 120

y = 120

Step-by-step explanation:

we know that,

Then,

33° + 87° + x = 180°

x = 180° - 120°

Now,

we know that,

Then,

x + y = 180°

60° + y = 180°

Hence,

The value of y = [120]°
