Caleb, the longest side of a right triangle is the hypotenuse.

x2 + (x + 5)2 = 252

x2 + x2 + 10x + 25 = 625

2x2 + 10x + 25 = 625

2x2 + 10x - 600 = 0

(2x + 40)(x - 15) = 0

2x + 40 = 0

2x = -40

x = -20

Since distance can't be negative, this answer is out.

x - 15 = 0

x = 15

Let's check.

152 + 202 = 252

225 + 400 = 625

625 = 625.

Check.
