Since a supplementary angle is 180 degrees do:
180 - 77
= 103 degrees
We should find the area of the carpet squares. Since each side is 1 foot, the area will be 1. Now, Julie used 120 carpet squares, which is 1 in area. So, we will have to multiply 1 by 120.
120×1=120
The area of the floor is 120 ft².
<span>2 cos theta = 1
Cos theta = 1/2
Inverse of cos (1/2) = 60 and 300 in degrees.
In radians we have
60 * pi/180 = 1.05
300 * pi/180 = 5.24</span>
