You can put this solution on YOUR website!
You have the measures of angle B, and the opposite side, side b. With that, one more piece of information (such as the measure of side a), and the law of sines, you can find all there is to know about triangle ABC.
sin%28A%29%2Fa=sin%28B%29%2Fb sin%28A%29%2F3=sin%2865%5Eo%29%2F8 --> sin%28A%29=3sin%2865%5Eo%29%2F8
My calculator gives me the (approximate) result for that calculation as 0.33986542.
It also tells me that the angle A should be (approximately) 19.86867495°.
So I guess the expected answer must be 20°, or maybe 19.9°.
