There are two points, A and B, whose elevations above datum are h₁ = 1710 ft and hß = 1425 ft and whose images a and b on a vertical photograph have photo coordinates = 2.95 in., y₁ = 2.32 in., x = -1.64 in., and y = -2.66 in. The camera focal length was 152.4 mm and the flying height above datum 7650 ft. On the same photograph, an image c of a third point C' appears. Its elevation hc = 1455 ft and its photo coordinates are x = 3.20 in. and Yc = -2.66 in. Compute the horizontal angles in triangle ABC.
