Answer 1

the angels are 60°,70°,50°.

Step-by-step explanation:

let the angels be 5x 6x and 7x

sum of angels =180°

5x+6x+7x=180

18x=180°

x=180/18

x=10°

putting the value of x we get

6×10=60°

7×10=70°

5×10=50°

Answer 2

Answer:

82) 75:100 = 15:20 = 3:4

83) 6x + 7x + 5x = 180⁰

18x = 180⁰

x = 10⁰

angles are 6×10 = 60⁰

7×10 = 70⁰

5×10 = 50⁰
