Question 785057: a lighthouse keeper is in the top of a lighthouse 95 feet above sea level. she notes that the angle of depression to a rock jutting above the water is 6 degrees. how far is the rock from the lighthouse Answer by mananth(16946) (Show Source):
You can put this solution on YOUR website!
vertical height = 95
angle of depression = 6 degrees
angle of elevation at rock = 6 degrees
horizontal distance to foot of tower = x
tan 6 = 95/x
x= 95/tan 6
x=904 feet
