Question

find the missing angles of the following polygons ​

Answer 1

Answer:

x+60°=180°

x=180°-60°

x=120°

Y=180°-70°

Y=110°

Answer 2

Answer:

x + 60° = 180° ( linear pair )

x = 180° - 60°

x = 120°

y + 70° = 180 ( linear pair )

y = 180° - 70°

y = 110°

w + x + y + z = 360° (angle sum property of quad.)

w + z + x + y = 360°

w + w + 120° + 110° = 360° (w = z)

2w + 230° = 360°

2w = 360° - 230°

2w = 130°

w = 130°/2

w = 65°

thus, w = 65°

x = 120°

y = 110°

z = 65°
