A wooden flagpole is imbedded 3 m deep at corner A of a concrete horizontal slab ABCD, square in form and measuring 20 ft on a side. A storm broke the flagpole at a point one meter above the slab and inclined toward corner C in the direction of the diagonal AC. The vertical angles observed at the center of the slab and at corner C to the tip of the flagpole were 65° and 35°, respectively, What is the total length of the flagpole above the slab in yards? A. 5.61 B. 16.83 C. 4.32 D. 12.38
