Answer:
Step-by-step explanation:
x=tan^-1(
)
It has to be in Quadrant 1 
or 3 
for positive.
Unless that incorrect due to tan(x) range is 
. Then the only answer is 
22 square feet !! hope this helps
For cosФ×sinФ =0, then either cosФ or sin Ф must be zero.
cos 90 = cos 270 = 0
sin 0 = sin 180 = sin 360 = 0.
So, the values that would give you 0 are:
1. cos 90 sin Ф
2. cos 270sin Ф
3. cos Ф sin 0
4. cos Ф sin 180 and
5 cos Ф sin 360.
