What is the answer to this somebody!!!
Fed [463]

Use the geometric mean for right triangles as the sides are related to the hypotenuse. 30 - 6 = 24. We need that for our proportion. \frac{24}{x}=\frac{x}{30}. We cross-multiply to get x^2=720. Taking the square root of both sides gives us that x=12\sqrt{5}, the second choice above.
