point be taken to the right of A, as O,we join O LMP; if to the left, as E, we join E KMP. OLMP and E RMP will always cut A C.Y. at the same pointBif EA = AO. So also, if we take a lesser distance, as AD, and makeAE = AD; join F RMP and D LMP; they will intersect in c,Now AO or AE = AB, hence B is… … Example 2.—Find a point 3 feet (3^) to right, 4 feet (4)within the P.P., and 5 feet (5^) above it. Height of spectator5 feet 6 inches (5 6), and his distance from P.P. 4 feet (4). BMP
