check the picture below.

since we know the angles at A and B, than the angle at F is just 180 - A - B.


\bf \cfrac{sin(F)}{f}=\cfrac{sin(B)}{b}\implies \cfrac{sin(85^o)}{7}=\cfrac{sin(60^o)}{b}\implies b=\cfrac{7\cdot sin(60^o)}{sin(85^o)}\\\\ -------------------------------\\\\ \cfrac{sin(F)}{f}=\cfrac{sin(A)}{a}\implies \cfrac{sin(85^o)}{7}=\cfrac{sin(35^o)}{a}\implies a=\cfrac{7\cdot sin(35^o)}{sin(85^o)}

make sure your calculator is in Degree mode.
