    a = 4.993

    c = 5.824

    A = 59°

    C = 90°

    Step-by-step explanation:

    b=3, B=31°

    Since it's a right angle.

    C = 90°

    A = 180-90-31

    A = 59°

    For side a and c

    a/sin A = b / sin B

    a = sinA * b/sin B

    a = sin 59 * 3/sin31

    a = 4.993

    a = 5

    c/sin C = b/sin B

    c = sin C * b/sin B

    c = sin90 * 3/sin 31

    c = 1 * 5.824

    c = 5.824
