    there's no way to solve that...there must be a right angle or something

    Are you trying to find the entire 3rd side of the triangle, or just the piece that is sticking above the circle?

    Oh, okay - well that is much easier! We'll need to use the Pythagorean Theorem (a^2+b^2=c^2), plug in our numbers and find the missing side. First off, we need to know which side is the hypotenuse (the longest side of the triangle - straight across from a right angle).

    Oh, wait - is this a right angle triangle? If it's not, you can't use the Pythagorean theorem.

    it does not indicate anything about a right triangle

    Okay - I completely understand what you're going through - I can't stand these type of problems that don't give you any extra info.! One sec . . . I'll see if I can figure this out.

    Remember that "tangent" means that there's a right angle? Well, since the 13200 and the 4000 sides come together, and are tangent, we know that they create a right angle. So, we know that our mystery side is across from the right angle, making that our hypotenuse. So, we're going to plug 13200 in for a^2 and 4000 in for b^2 and see what we get. When we square each: a=174240000 and b=16000000 Now, we'll add them together: 190240000 Okay, now we're looking for c^2. Here's our equation so far: 190240000=c^2 All we need to do now, is take the square root of each side, and we find that c=13792.75172 Hope this helps!

    I didn't round the answer - I'm not sure if you wanted it to be rounded.
