Question 1122789
Find x the angle of depression from the top of a lighthouse that is 184 ft above water level to the waterline of a ship 970 off shore.
 Round your answer to the nearest tenth of a degree.
:
We can find the interior angle (A) that is associated with the angle of depression using the tangent
tan(A) = {{{970/184}}}
A = 79.3 degrees
therefore
90-79.3 = 10.7 degrees is the angle of depression
