**Steve**, Thursday, July 11, 2013 at 10:14amassuming the angles are to the flagpole

draw a diagram. If the distance from the building is x and the building has height h,

(h+25)/x = tan61°30'

h/x = tan56°20'

equating values of x, we get

(25+h)56°20' = h tan61°30'

1.50133(25+h) = 1.84177h

h = 110.25
