$i n A {\overset{Δ}{B}}_{} C : \frac{b - c}{h_{a}} = k,$ $a n d \hat{A} i s g i v e n .$ $\hat{B}, \hat{C} = ?$

	$C = 180 ° - A - B$ $c = \frac{h_{a}}{\sin B}$ $b = \frac{h_{a}}{\sin C}$ $\frac{b - c}{h_{a}} = \frac{1}{\sin C} - \frac{1}{\sin B} = k$ $\Rightarrow \frac{1}{\sin (A + B)} - \frac{1}{\sin B} = k$ $w e c a n s o l v e f o r B o n l y n u m e r i c a l l y .$
