SSA and geometry

The distance between the points P and Q was 356 m measured in the terrain. The PQ line can be seen from the viewer at a viewing angle of 107° 22 '. The observer's distance from P is 271 m. Determine the viewing angle of P and observer.

Correct answer:

Q =  46.5966 °

Step-by-step explanation:

R=107+6022=303221107.3667  r=356 m q=271 m  sin(R)sin(Q)=rq  s=sin(Q) s=rq sinR=rq sin107.36666666667° =356271 sin107.36666666667° =356271 0.954414=0.72653  Q=π180°arcsins=π180°arcsin0.7265=46.5966=46°3548"
