Answer:
x = 15
Step-by-step explanation:
We assume you want to find the value of x.
Know (or prove) that in this geometry, all of the right triangles are similar. That means the ratios of corresponding sides are proportional.
short side / hypotenuse = 9/x = x/25
x^2 = (9)(25) . . . . . . . . . . multiply by 25x ("cross multiply")
x = √((9)(25)) = (3)(5) . . . take the square root
x = 15

Answer:
5 kilometers south
Step-by-step explanation:
5 kilometers east 5 units right
5 kilometers north 5 units up

The right and left cancel so we are left 5 units up at this time
we are 5 units north at this time
To get back we must go 5 units down, which is 5 km south
