A right triangle has one leg with a length of 5 units. The hypotenuse is 30 units long. What is the length of the other leg?

I'm not exactly sure but the Hypotenuse is always the longer leg of the right angle triangle. Labeled H and the leg labeled opposite (O) is always across from the 90 degree angle of the triangle. Leaving the only leg left of the triangle to be labeled adjacent. This is a more advanced way of solving the Pythagorean theorem.

Answer, C

Step-by-step explanation:

5 squared is 5*5 which is 25then the hypotenuse which is 30 times 30 equals 900now we need to find the middle of our equation.√87525 plus √875 = 900so your answer is C √875
