draws the right triangle
A on the left, B on the right, C directly above B.
Hypotenuse AB goes northeast.
opposite is BC = 11, hypotenuse is 12.
then AC is sqrt(23) by pythagorean
sin B = sqrt(23)/12
sin C = sin 90 = 1

Yeah, without a diagram or specification, we can't assume we have a right triangle ABC, with C being the right angle
