The length of one leg of a right angle triangle is 3 in more than the other. if the length of the hypotenuse is 15 in, what are the length of the two legs?

The first thing you need to remember is this equation 3^2+4^2=5^2.This equation is correct.You can check it using Pythagorean Theorem.(a^2+b^2=c^2)

So the hypotenuse is 15 right.One length is 3 more than the other right.So what I did was proportions.The hypotenuse of 3^2+4^2=5^2 is 5 units.This one is 15.So I multiplyed each leg by 3.And it gave me 9^2+12^2=15^2.This is correct because one Leg is 3 units more than the other one.

1st leg- 9 units
2nd leg-12 units
3rd leg-15 units
