Answer 1

12

Explanation:

20 is the hypotenuse and 16 is the leg, first solve 20^2 (20x20) to get 400 and 16^2 (16x16) to get 256, then subtract the leg from the hypotenuse to obtain 144 (400 - 256) then obtain the square root of 144 (
`√(144)`) then 12 will be the awnser.

Answer 2

The answer would be x=12
