Answer the following questions based on the graphic and information given below. In the figure above a surveyor wants to know the distance from the top of the tower to the bottom of the tower.

If the angle of declination is known, a surveyor would use
to find the length x. The cosine of a 50° angle is
this represents the value created when length
is divided by
feet. If the angle of declination changed to 60°, the cosine would be 0.5; now the length of x would be
feet. If the angle of declination changed to 60°, the angle of inclination would be
degrees.
