1. ## trig ratio

In triangle PQR, sin P=0.15 and sin Q=0.5 Find the ratio q : p

In $\Delta PQR\!:\;\;\sin P\:=\:0.15\:\text{ and }\:\sin Q=0.5$
Find the ratio $q : p$
We're expected to know the Law of Sines: . $\frac{q}{\sin Q} \:=\:\frac{p}{\sin P}$
So we have: . $\frac{q}{0.5} \:=\:\frac{p}{0.15} \quad\Rightarrow\quad \frac{q}{p} \:=\:\frac{0.5}{0.15} \:=\:\frac{50}{15} \:=\:\frac{10}{3}$
Therefore: . $p:q \:=\:10:3$
