In ABC, <A is a right angle, and m<B = 45*. What is the length of bc?
A.14ft
B.14/2ft
C.14/3ft
D.28ft
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.
Answer: A. 14ft
