The tangent of an acute angle of a right triangle is the ratio of the length of the opposite leg to the length of the adjacent leg. tan (42.3) = 13.8/CB tan (42.3)* CB = 13.8 CB = 13.8/[tan(42.3)] CB = 12.56

Checking: tan(42.3) = .9099 13.8 divided by .9099 = 13.8 divided by .9099 = 15.1665018 Yes. Thank you for catching my error.

tan (42.3) = 13.8/CB tan (42.3)* CB = 13.8 CB = 13.8/[tan(42.3)] CB = 13.8/.909 CB = 15.167
