    think of it in terms of what you want to find, not what you know already. You know an angle...how is that angle related to side BC?

    ohh would the side measure the same as the angle or double?

    So it would be double the angle degree?

    in terms of the angle and missing side x, are they next to each other or across from each other?

    yes, you told me before that 6 was the hypotenuse and then you just discovered the angle and the missing side were opposite. so you would use sine.
