From a point 150 ft from the base of a building the top and the base of a flagpole on a roof edge have angles of elevation of 27degrees49' and 21degrees42' respectively. Find the height of the pole.

Answer 1

height of building from ground:

tan 21 42/60 = h/150

height of flagpole top from ground:

tan 27 49/60 = H/150

then height of pole = H-h

Answer 2

22.115
