 Question 386773: Alright, this is kind of hard to explain, but I'll try to do my best. I have a triangle. It's slanted. The side to the far left (looks kind of like a base) is side x. across from the "base" there's a segment, used so that it splits the ttriangle into one smaller triangle and one smallish quadrilateral. The length of this segment is 8. The top of the quadrilateral is y, the bottom is 4. The top part of the smaller triangle is 5, and the bottom part is 7. I'm supposed to find x and y. I've attempted calling it a midsegment, however the segment does not bisect anything. I can't use the pythagorean theory because I can't tell if it's a 90 degree angle or not. Please help!
