  1. Angle A is 30 more than twice angle B can be written as

    A = 2B + 30

    Because we know that angle A and angle B form a linear pair, we know that

    A + B = 180

    Plug the first equation into the second equation and solve for A. Once you solve for A, plug the know A value into into second equation and solve for B.
