Answer:

x=20

Step-by-step explanation:

The Pythagorean theorem is

a^2 +b^2 = c^2

where a and b are the legs and c is the hypotenuse.

The legs are x and 15 and the hypotenuse is 25

x^2 + 15^2 = 25^2

x^2 +225 = 625

Subtract 225 from each side

x^2 +225-225 = 625-225

x^2 = 400

Take the square root of each side

sqrt(x^2) = sqrt(400)

x = 20

With right triangles, a^2+b^2=c^2

c is the hypotenuse, or longest side.

In this case:

c=25

b=15

So, square these numbers:

15 squared is 225

25 squared is 625

625-225=400

The square root of 400 is 20

So:

x=20
