If you make yourself a diagram, you would see that the base and the ladder length are given...this would be the adjacent side and the hypotenuse...the trig function these relate to is the cosine function...
cos(theta) = adjacent/hypotenuse
cos(theta) = 2/12 = .166666...
now take the inverse cosine and get
theta = 80.4 degrees
