a right triangle has a hypotenuse of length 25 and a leg length of 15. what is the length of the other leg? if necessary, round you answer to two decimal places

Answer 1

Let the leg lengths be a and b and the hypotentuse be c. a = 15 is the leg length that you know.

Use the Pythagorean right-triangle equation

b^2 = c^2 - a^2 = 625 - 225 = 400

Solve for b.

Rounding off will not be necesary in this case.
