Answer:8) 76°

9) 88°

Step-by-step explanation:

Sum of exterior angles of any polygon is 360°

Exercise 8

Sum of given angles:

2x + 60° + 64° + 36° + 48° = 360°

2x + 208° = 360°

2x = 360° - 208°

2x = 152°

x = 76°

Exercise 9

Sum of given angles:

x + 90° + 109°+ 73° = 360°

x + 272° = 360°

x = 360° - 272°

x = 88°
