7. In the triangle \(A B C , A B = 8 \mathrm {~cm} , A C = 7 \mathrm {~cm} , \angle A B C = 0.5\) radians and \(\angle A C B = x\) radians.
- Use the sine rule to find the value of \(\sin x\), giving your answer to 3 decimal places.
Given that there are two possible values of \(x\),
- find these values of \(x\), giving your answers to 2 decimal places.
