A vertical tower stands on a horizontal plane and is surmounted by a flagstaff of height 7 m. At a point on the plane, the angle of elevation of the bottom of the flagstaff is 36° and that of the top of the flagstaff is 45° .Find the height of the tower.
P.S:-I constructed a diagram but I am not able to deal with 36° without using trigonometric table. Pls. help.
