x=5

Step-by-step explanation:

a^2 + b^2 = c^2

c^2 - a^2 = b^2

13^2 - 12^2 = b^2

169 - 144 = b^2

25 = b^2

5 = b

x = 5

Step-by-step explanation:

Pythagorean theorem

Hypotenuse² - Side 1² = Side 2²

Side² + side² = Hypotenuse²

More commonly written with

c² - a² = b²

c² - b² = a²

a² + b² = c²

b² + a² = c²

c represnts the hypotenuse

a and b are sides

Now with that in mind if we want to find the unsquared value we square root both sides, and because we're finding a side we'll use hypotenuse minus the given side.

where as b is the unknown side
