Question 1117064: A land scaper sights the top of a tree at a 68 degree angle.she then moves an additional 70 feet directly away from the tree and sights the top at a 43 degree angle.how tall is the tree to the nearest tenth of a foot. Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! A landscaper sights the top of a tree at a 68 degree angle.she then moves an additional 70 feet directly away from the tree and sights the top at a 43 degree angle.how tall is the tree to the nearest tenth of a foot.
------
height = base*tan(68)
height = (base+70)tan(43)
------
base*tan(68) - base*tan(43) = 70*tan(43)
base = 70*tan(43)/[tan(68)-tan(43)] = 42.32
----
Ans:: height = 42.32*tan(68) = 104.74 ft
