Question

Find the unknown angles in the given figure

Answer 1

Answer:

120 degree = y+ 70 degree{exterior angle property}

y=120-70

y=50 degree

x+120 degree =180{linear pair}

x=180-120

x=60 degree

Answer 2

Answer:

Angle x +120 = 180 (linear pair)

X=180-120

X=60°

60+70+y=180(sum of angles of a triangle)

Y=180-130

Y=50°
