Answer:

  D.  45

Step-by-step explanation:

Without a diagram, we can only assume that C is the hypotenuse of a right triangle with legs A and B. If that is the case, then the length of C is given by the Pythagorean theorem:

  C^2 = A^2 + B^2

  C^2 = (34 ft)^2 + (29 ft)^2

  C^2 = 1997 ft^2

  C = √1997 ft ≈ 44.69 ft

The length of beam C is about 45 feet.
