a lifeguard sits on the lifeguard stand that is about eight feet high.he suddenly notices that a swimmer is struggling in the water.the angle between the base of the lifeguard stand and the swimmer is about 102 degree,and the straight line distance between the base of the stand and the swimmer is about 85ft. how far is the lifeguard from the swimmer?

I can't figure out the 102° angle. Describe the scene, labeling each point of interest and relevant distances and angles.
an angle between two points makes no sense.
