Answer 2

let ratio be x

so,

5x,3x,7x

a/Q

5x+3x+7x=180°(by ASPT)

15x=180°

x=180÷15

x=12

putting the value of x

5x=5×12=60°

3x=3×12=36°

7x=7×12=84°

as we know that about acute angle

it is greater than 0°but less than 90°

so,all the value of x is less than 90°..

so, it is acute angled traingle..
