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
