Answer:
A.22.52 units
Step-by-step explanation:
We will use the Pythagorean theorem to solve this. The Pythagorean theorem states that the sum of the squares of the two legs of a right triangle is equal to the square of the hypotenuse.
The two legs are x and 13 and the hypotenuse is 26; this gives us
x²+13² = 26²
x²+169 = 676
Subtract 169 from each side:
x²+169-169 = 676-169
x² = 507
Take the square root of each side:
√(x²) = √507
x ≈ 22.52
