The m angle A is 30 more than twice angle B. If angle A and angle B form a linear pair, find the measure of both angles.

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.
