Circle $$D$$ is below. What is the arc measure of minor arc $${B C}$$ in degrees? ![](http://admin.getprephub.com/media/editor/ci6_20230216203427850761.png)

Solution $$m< A D C+m< A D B+m< B D C=360^{\circ}$$ Or, $$(13 n-16)+(7 n+12)+6 n=360$$ Or, $$26n-4=360$$ Or, $$26n=360+4$$ Or, $$=\frac{364}{26}=14$$ The arc measure of minor arc $${B C}$$ in degrees $$=6 n=6 \times 14=84^{\circ}$$
