Aroofer is standing on the roof of a house 60 ft above the ground. his truck is parked 25 ft from the house. what is the angle of depression from the roofer to his truck?

Angle of depression is the angle that is created below the horizontal with your line of sight. to solve the angle of depression, use the formula:
tan(d) = o / a
where d is the angle of depresion
h is the opposite side of the angle which is the height 60 ft
a is the adjacent side of the angle which is 25 ft

tan( d ) = 60 / 25
d = arctan ( 60 / 25)
d = 67.38 degrees
