    Use the definition of the cosine in a right-angled triangle.

    the person makes a right triangle with the base and top of tower height is the opposite side from the angle side 100 ft is adjacent side to angle tan(60) = opposite/adjacent = h/100 h = 100*tan(60) b) tan(x) = h/200 x = inverseTan(h/200), use h found above
