1. The problem statement, all variables and given/known data The problem is attached as TheProblem.jpg and the answer is D. 2. Relevant equations Perhaps the equations attached in Metric relationships summary.pdf. 3. The attempt at a solution My logic is as follows: For A, XW does not necessarily equal WZ. For B, it seems that they are trying to trick the student into thinking of h^2 = d*e (from the Metric relationships summary.pdf file). For C, the ratio does not work out because the angle facing each respective smaller/larger leg is different. For D, I can't figure it out but it seems to relate to the Metric relationships summary.pdf file I attached. Any input would be greatly appreciated! Thanks in advance!
