Since <A is a right angle and <B is 45*, then <C = 180 - 90 - 45 = 45 degrees.
In a right triangle, if two angles are the same, then the two sides opposite those angles are congruent.
Therefore, bc and ac are congruent.
Since ac is a side of the right triangle ABC, ac = 14 ft.
Therefore, the length of bc is also 14 ft.
