An inaccessible cliff was sighted from point A. The angle of elevation was observed to be 18.45°. The surveyor went closer to the edge of the cliff at point B. Point B is 425m nearer but 25.6m lower than A. The angle of elevation was observed to be 36.3° from B. If the elevation of A is 602m, what is the elevation of the top of the cliff?
