The hypotenuse of a right triangle is 15cm, and the shorter leg is 9cm. Find the length of the other leg
pishuonlain [190]

Hello!

If you add up the squares of the two legs, it will equal the square of the hypotenuse. As we already have the hypotenuse, we will subtract.

225-81=144

Now we find the square root.

√144=12

Therefore, the other leg is 12 cm long.

I hope this helps!
