The sides of triangle are in ratio 5:3:4 and it's perimeter is 180m find altitude of the triangle corresponding to its largest side

Answer 1

this is just a right triangle with longest leg length 4. (Hypotenuse is 5)

5+3+4 = 12
180/12 = 15

So, scale it up by a factor of 15, and its sides are

75:45:60
