    First, add up the 7 and the 9: 16 Now, in this problem we can see that the hypotenuse (or longest side) is the 16. So, that will go in for c^2. Here's what we have in our Pythagorean theorem equation: a^2+15^2=16^2 Okay, let's square these: a^2+225=256 Next, subtract 225 from 256: a^2=31 Next, we need to take the square root of both sides: a=5.567764 (rounded)

    Note: a is the same as x - sorry, this might seem confusing.
