The hypotenuse of a right triangle is  25 cm, and the shorter leg is 15 cm. Find the length of the other leg.

Answer:

The other leg is  20 cm

So the equation for the Pythagorean theorem is

a^2+b^2=c^2

The hypotenuse is always the c. It does matter if 25 is plugged into a or b. So

15^2=225 and c^2=25^2=625

So subtract 225 from both sides. You have a^2(or b^2)=400. Square root on both sides. There, a^2(or b^2), i.e. the other leg, is 20 cm.
