Question

In a triangle , the ratio of angle s is 3:7:5. Find the measure of all the angles?​

Answer 1

Answer:

3x + 7x + 5x = 180

15x = 180

x = 180/15

x = 12

angle 1 = 12 * 3 = 36

angle 2 = 12 * 7 = 84

angle 3 = 12 * 5 = 60

Answer 2

Answer:

36, 84 and 60

Step-by-step explanation:

let first , second and third angle be 3x ,7x and 5x respectively.

3x+7x+5x = 180

15x = 180

x= 12

3x = 3×12= 36

7x = 7×12 = 84

5x=5×12 = 60
