    I found angle c by adding angle a and angle b and subtracting that from 180

    a/sina=b/sinb=c/sinc b/sin(110)=50/sin47 solve the right half of the equation and then multiple it by the sin(110) and you will get side b

    just take 50/sin47 and find what that equals then multiply that by the sin110
