Can anyone explain this math problem to me? How would I solve for “x”? I know that I have a large Right Triangle which has been bisected on its Right Angle to create two, smaller Right Triangles. Since each (of these smaller triangles) would then have two angles measuring 45 Degrees, doesn't it mean that I’m dealing with two 45-45-90 Triangles (the legs of the triangles are equal)? Based on this reasoning, I’m confronted by a conundrum because that gives me two values for “x”, 9 & 6 — which is obviously an error. Could anyone more apt at math than myself help me grasp the solution to this problem?
