14.7
To find the missing side length, we can use the Pythagorean Theorem which states that in a right triangle, the sum of the squares of the two shorter sides is equal to the square of the longest side (the hypotenuse).
Let the unknown side be x. We know that one side is 15 and the other is 3. So, we have:
15^2 = 3^2 + x^2
225 = 9 + x^2
216 = x^2
x = sqrt(216) ≈ 14.7
Therefore, the unknown side length is approximately 14.7.
Use the image to answer the question.
