Weegy: 7, 24, 25 will form a right triangle according to the Pythagorean Theorem.
User: One leg of a right triangle is 12, and the hypotenuse is 20.
The length of the other leg is a0.
Weegy: The answer is 15. The length of the hypotenuse of a right triangle with legs of lengths 9 and 12 is 15. (9^2+12^2=15^2)
(More) 8
One leg of a right triangle is 12, and the hypotenuse is 20.
a^2+b^2=c^2
12^2+b^2=20^2
144+b^2=400
b^2=400-144
b^2=256
b=16
Therefore, the length of the other lef is 16.
