Solve the problem.A pole of length L is carried horizontally around a corner where a 5-ft-wide hallway meets a 6-ft-wide hallway. For 0 < ? < 
, find the relationship between L and ? at the moment when the pole simultaneously touches both walls and the corner P. Estimate ? when L = 18 ft. Round the result to three decimal places. 
A. L = 5 cot ? + 6 tan ?; ? ? 0.300, 1.215 B. L = sec ? + 11 csc ?; ? ? 0.721, 1.425 C. L = 6 sec ? + 5 csc ?; ? ? 0.458, 1.060 D. L = 5 sec ? + 6 csc ?; ? ? 0.511, 1.113
