grandnat_6: By the way, numbers less than 1 must always have a zero before the decimal point. E.g., 0.57, not .57. See the international standard (ISO 31-0); or see any credible text book.

Regarding your question in post 30, the black equation is incorrect. It should not have x and y subscripts. See the blue text in my analysis06.png file to see why, and to see the correct algebra.

All answers in both attached files currently appear to be correct.

Could you also provide dimensions xC, yC, xD, yD, xG, and yG, shown in the attached file? You can just list them; you do not necessarily need to draw them again.
