Question

Find angle sum therom ​

Answer 1

Step-by-step explanation:

we know that,

• sum of all angles of triangles is equal to 180°

Then,

33° + 87° + x = 180°

x = 180° - 120°

x = 60°

Now,

we know that,

• sum of all angles which lies on a straight line is equal to 180°

Then,

x + y = 180°

60° + y = 180°

y = 120°

Hence,

The value of y = [120]°

Answer 2

Answer:

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
