A telephone pole stands exactly in the middle between two houses. The houses are 72 feet apart. If a wire is stretched from the top of the pole to the base of the house, its length is 39 feet.

1. A. is correct.
   
   B. the height of the pole is not 39 feet; that's the length of the wire.
   
   a^2 + b^2 = c^2
   
   a^2 + 36^2 = 39^2
   a^2 + 1,296 = 1,521
   a^2 = 1521 - 1296
   a^2 = 225
   a = 15 feet
