There are two points, A and B, whose elevations above datum are hд = 1610 ft and hß = 1425 ft and whose images a and b on a vertical photograph have photo coordinates x₁ = 2.95 in., Ya 2.32 in., x = -1.64 in., and y xb -1.64 in., and yɩ = −2.66 in. The camera focal length was 152.4 mm and the flying height above datum 7550 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 y = -2.66 in. Compute the horizontal angles in triangle ABC. ་་ Part A Compute angle A. Express your answer in degrees to six significant figures. A = ΜΕ ΑΣΦ. Η vec 0 ?
