That's basic trigonometry
Tangent 57 degrees = AC / 9
AC = Tangent 57 degrees * 9
AC = 1.5399 * 9
AC =
13.8591
Rounding to one tenth =
13.9

Soh Cah Toa! :)
Sin = Opposite/Hypotenuse
Cos = Adjacent/Hypotenuse
Tan = Opposite/Adjacent
You are looking for AC, which is opposite. And you are given Adjacent.
tan(57)*9 = length of B which is 13.85 units
