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

let h be the height
Using Pythagoras,
h^2 + 36^2 = 39^2
h^2 = 225
h = 15
Using Pythagoras,
h^2 + 36^2 = 39^2
h^2 = 225
h = 15
