Question

Find the measure of angles x, y and z.

Answer 1

Answer:

x=(180-120)°=60°

y={180-(70+60)}°=(180-130)°=50°

z=(180-50)°=130°

Answer 2

Answer:

x+120°=180°. [linear pair]

x=60°

z=70°+x. [exterior angle of a triangle is the sum of the two opposite interior angles]

z=70°+60°

z=130°

120°=70°+y. [exterior angle of a triangle is the sum of the two opposite interior angles]

y=50°
