Finding the square root of a number is the inverse operation of squaring that number. Remember, the square of a number is that number times itself. The perfect squares are the squares of the whole numbers. The square root of a number, n, written below is the number that gives n when multiplied by itself.
Answer:
9 in, or B
Step-by-step explanation:
We can easily apply the Pythagorean Theorem to this. You could either realize that this is a 3-4-5 Pythagorean triple or do the math by hand.
We start off by setting up the equation 12² + x² = 15². Simplifying, we get 144 + x² = 225, and then x² = 81 after subtracting 144 from both sides. Thus, the square root of x is 9, and so the answer is 9 inches.
