In a triangle ABC, the angle at A is 41 degrees, the angle at B is 71 degrees, and the length of side AB is 8. To 2 decimal places, what is the length of side BC?
I got this answer 5.66. is that correct? I used sinerule.

Using sine rule, $\frac{AB}{\sin 68^\circ}=\frac{BC}{\sin 41^\circ}$ so your answer is correct.
