Answer 2

Answer:

a)Sum of angles of a pentagon =540°

2x+30°+110°+120°= 540°

2x = 540°-260°

x = 140°

b)Sum of angles of a quadrilateral = 360°

90°+70°+60°+x = 360°

x = 360°-220°

x = 140°

c)Sum of two opposite interior angles = Exterior angle

y = 120°

x = 150°

z = 90°

d)Sum of angles of a quadrilateral = 360°

w=100°

x= 60°

y=100°

z=120°
