Question

if the sides are in the ratio 5:3:4,prove that it is a right angled triangle.​

Answer 1

Step-by-step explanation:

let the angle be x

5x+3x+4x=180 degree

12x =180 degree

x = 180/12

x =15

now substitute the values:

5x = 5 X 15(it is the value of x) =75

3x =3 X 15= 45

4x = 4 X 15= 60

that's it! hope it helps!
