Question

Find X using angle sum theory.

Answer 1

Step-by-step explanation:

As we know that -

The sum of all angles of a triangle is 180°

Then,

87° + 33° + x = 180°

x = 180° - 120°

x = 60°

Hence,

The value of x = [60]°

Answer 2

Answer:

x = 60°

Step-by-step explanation:

sum of internal angle = 180

x + 33 + 87 = 180

x = 180 - 87 - 33

x = 60°
