OCR: Solution: Case 1. In the edge-on drawing shown above we have: CD = Earth-Sun distance = 1.5 x 100 km CA = CB = radius of Sun = 7.0 x 105 km LABC = 300 and CD bisects ZACB Let AE be the perpendicular from A to CD and let h be its length. Then CE = h cotZACE; ED = h cot ZADE; and h = CA sin ZACE. (Solution continued next card.)
