$Triangle ABC with angle A = 35 degrees, angle B = 85 degrees, and side a = 10, with side b to be found$

In triangle $ABC$ , angle $A = 35\degree$ , angle $B = 85\degree$ , and side $a = 10$ . Use $\sin(35\degree) \approx 0.574$ and $\sin(85\degree) \approx 0.996$ . Find side $b$ . Round to the nearest tenth.
