A man standing 20 m from a tower estimates the angle of elavation of the top and bottom of a flagpole on the tower as 58 degrees and 55 degrees. Calculate the height of the flagpole.
How would I go about finding the height of the flagpole?
Calculate the height of the bottom:
tan55= hb/20 solve for hb
Calculate the height for the top
tan 58=ht/20 calculte ht
The difference between ht and hb is the height of the flagpole.
