The statement <span>The coefficient of x^k y^n-k in the expansion of (x+y)^n equals (n-k / k) is true. This will show the standard formula and the expansion of it. We all know that it can still be expanded based on the power or degree of the terms.</span>

To answer this problem, you need to use SOHCAHTOA. The pole, the tent, and the ground form a right triangle. One leg is equal to 5. The top angle is 55. You need to find length of the other leg, so use tangent.
tan55=O/5
O=0.4375
Double this to find the total width of the tent. 0.4375*2=0.875
0.875 (rounds to 1) feet
Hope this helps!!
