The hypotenuse of a right triangle is 15 cm, and the shorter leg is 9 cm. Find the length of the other leg.

We need to use the pythgorean therum (or however it is spelled)

a^2 + b^2 = c^2 ... where a and b are the legs and c is the hypotenuse

9^2 + b^2 = 15^2

81 + b^2 = 225

b^2 = 225 - 81

b^2 = 144 ... take square root of both sides, eliminating the ^2

b = sqrt 144

b = 12

so ur other leg is 12 cm

12 cm

Using the pythagorean theorem, it is possible to find the length of the remaining leg.

a^2 + b^2 = c^2

In this case c=15 and a=9.

Solve for b and you get 12, which is your answer.
