Answer the following questions based on the graphic and information given below.
90 feet
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
y 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.
