1. The problem statement, all variables and given/known data Hi, I have inserted a picture of the problem: I have to find x, the altitude, or height of the triangle. x is the height of the larger triangle, and is perpendicular to the base of 13. It divides the base into segments of length 4 and 9. This was a question on my math assessment test for community college. But I couldn't think of an answer, so I left it blank. It's impossible to find x without more information, such as the length of another leg of the triangle. If the other leg were y, then: x = (y + 4)(y - 4) but there is no y variable given.
