    Angles in a triangle add up to 180 degrees.

    therefore the third angle will be 180-14-34 = 132

    use the sine rule:

    30/sin(132) = B/sin(14)
    30sin(14)/sin(132)=B
    9.76614 = B


    30/sin(132) = A/sin(34)
    30sin(34)/sin(132)=A
    22.474 = A

    Side A = 22.47 (2dp)
    Side B = 9.77 (2dp)
