A communications satellite is directly above the extension of a line between receiving towers A and B. It is determined from radio signals that the angle of elevation from tower A is 88.9 degrees

 

88.9° and the angle of elevation from tower B is 86.9 degrees

 

86.9°. If A and B are 694

 

694 km​ apart, how far is the satellite from​ A?

​(Ignore the curvature of the​ earth.)

A satellite is above two points, A and B. A line rises from left to right from B to the satellite and another line labeled ? rises from left to right from A to the satellite. A horizontal dashed line extends to the right from point B, through point A. The distance between points A and B is labeled 694 kilometers. The smallest angle that extends clockwise from the line connecting B to the satellite to the horizontal line measures 86.9 degrees. The smallest angle that extends clockwise from the line connecting A to the satellite to the horizontal line measures 88.9 degrees.
