Answer 1

I just worked this problem for somebody. I'll check and see if I can find my work.

Answer 2

Okay(:

Answer 3

If the altitude is drawn to the hypotenuse of a right triangle, the length of either leg is the geometric mean between the hypotenuse and the segment of the hypotenuse adjacent to the leg.If the altitude is drawn to the hypotenuse of a right triangle, the length of either leg is the geometric mean between the hypotenuse and the segment of the hypotenuse adjacent to the leg.

8/JK = JK/16

(JK)^2 = 8*16

JK = 8√ 2 units
