Answer 1

Answer:

a) 50° + 130° + 120° + x = 360°

x + 300° = 360°

x = 60°

b) 70° + 60° + 90° + x = 360°

x + 320° = 360°

x = 40°

c) 180° – 60° = 120°

180° – 70° = 110°

120° + 110° + 30° + x + x = 450°

260° + 2x = 450°

2x = 190°

x = 145°

d) All the sides are equal,

x + x + x + x + x = 450°

5x = 450°

x = 90°
