Compute angle $A.$

Express your answer in degrees to six significant figures.

There are two points, A and $B,$ whose elevations above datum are $h_A=2010ft$ and

$h_B=1425ft$ and whose images a and $b$ on a vertical photograph have photo

coordinates $x_a=2\mathrm{.}95$ in$.,y_a=2\mathrm{.}32$ in$.,x_b=-1\mathrm{.}64$ in$.,$ and $y_b=-2\mathrm{.}66$ in$.$ The

camera focal length was $152\mathrm{.}4mm$ and the flying height above datum $7950ft.$

On the same photograph, an image $c$ of a third point $C$ appears. Its elevation

$h_C=1455ft$ and its photo coordinates are $x_c=3\mathrm{.}20in.$ and $y_c=-2\mathrm{.}66in.$
