For question 21) it was missing the diagram of the problem. Looking at the solution, I disagree, because triangles AEH and EFH are not congruent, they share the same base, but have different heights, therefore, we cannot have our solution as the sum of triangles EFH and CHG. I suggest putting the diagram onto a graph and finding the co-ordinates of H, so that you can insert more lengths.

Thanks for posting.

The figure was on the test before. It is as follows.

Please post any question you have. Thanks again!
