Question

17. If the angles of a pentagon are in the ratio 7:8:11:13:15, find the angles.
​

Answer 1

Answer:

70°,80°,110°,130°,150°

Step-by-step explanation:

let common factor be x

ratio=7:8:11:13:15

total angle in pentagon=540°

so,

7x+8x+11x+13x+15x=540°

=>54x=540°

=>x=10°

hence,

7x=70°

8x=80°

11x=110°

13x=130°

15x=150°
