The hypotenuse of a right triangle is 15 cm long. One of the triangles legs is two times the length of the other leg. Find the lengths of the three sides of the triangle.

The first leg would be 3 times the square root of 5 cm

The second leg would be 6 times the square root of 5 cm

The third would obviously be 15 cm

3^2 = 9 Square root of 5^2=5 together = 45

6^2 = 36 Square root of 5^2=5 together = 180

15^2 = 225

45+180=225
