A tree growing on a hillside casts a 121-foot shadow straight down

the hill. Find the height of the tree (in feet) if the slope of the hill is 8 degrees
and the angle of elevation of the sun from the horizontal is 50degrees.

see whether you can figure how I developed the required formula for the height h of the tree:

h = 121(cos8°tan50° - sin8°) = 126 ft

Draw a diagram and figure out some of the distances.
