Question

Find the value of x.

Answer 1

Explanation:

This is a right triangle; so you can use the Pythagorean Theorem (
`a^2 + b^2 = c^2`), where a and b are the lengths of the legs and c is the hypotenuse.

You get:
`5^2 + 12^2 = c^2`

Simplify the expression:
`25 + 144 = c^2`

Combine like terms:
`169 = c^2`

Take the square root of both sides:
`√(169) = √(c^2)`

Evaluate: 13 = c

So the answer is letter c ... x = 13
