    if we divide both sides by 3 we have 3 and 5 this is a triangle 3-?-5

    so 5^2 + 3^2= c^2

    15^2=9^2+x^2 225-81=x^2 144=x^2 x=12

    in normal cases you cud use the rate of a 3-4-5 triangle we noticed that we have 3-?-5 so its 3-4-5 hancere verse the calculation made b4 by multiplying by 3 4(3)=12
