the shorter leg of a right triangle is 5 yards.if the hypotenuse is 13 yards,how long is the other leg?

• math -

Use the following:

a^2 + b^2 = c^2

a^2 + 5^2 = 13^2

a^2 + 25 = 169

Subtract 25 from both sides (whatever operation you do to one side of an equation you must do to the other side as well):

a^2 = 144

Take the square root of both sides:

a = 12

Hope this helps.
