Question

The angles of triangle are in ratio of 5:3:7, the triangle is

Answer 1

Answer:

the sum of angle of triangle is 180 .

we take a common ratio x

then 1st angle be 5x second be 3x nd rthird be 7x.

then 5x+3x+ 7x = 180

15x = 180

X = 180/15

x= 12

angle = 12×5 = 60

12×3 = 36

12×7 = 84.

follow me if it help

Answer 2

Step-by-step explanation:

Let the common multiple be a

So, the angles are 5a, 3a and 7a

5a + 3a + 7a = 180 ( angle sum property)

15a = 180

a = 180/15

a = 12

Angles are

5a = 5x12 = 60°

3a = 3x12 = 36°

7a = 7x12 = 84°

I hope it helps
