Answer:
AB=4.7, BC=8.8, \angle C=28^(\circ)

Explanation:

As angles in a triangle add to 180 degrees,


\angle C=180^(\circ)-90^(\circ)-62^(\circ)=\boxed{28^(\circ)}

We know that:


\sin 62^(\circ)=(BC)/(10)\\\\BC=10\sin 62^(\circ) \approx \boxed{8.8}

Similarly,


\cos 62^(\circ)=(AB)/(10)\\\\AB=10\cos 62^(\circ) \approx \boxed{4.7}
