Using the side length as the hypotenuse of a right triangle and half the given angle as the adjacent angle. Find the length of the base of a right triangle. This would be half the length of BD.
Cos(60) = adjacent leg/ 10
adjacent leg = cos(60) x 10
Adjacent leg = 5
Length of BD = 5x 2 =
10

Well, first thing's first: find the area.
The formula for area is L*W
L=9 ft
W=6 ft
9*6=54 sq ft
Since the area is 54 sq ft, and each small glass square is 1 sq ft, you would need A) 54 squares of glass
