s_1 =s_2 =s  ((TS)/(PR))=((QT)/(QP))⇒TS=((41)/3)  a=∠QST ,r=∠QST=∠PRQ  ((SQ)/(sin(a)))=((14)/(sin(R)))  ((28)/(sin(s)))=((ps)/(sin(a)))  ((PS)/(sin(R)))=((41)/(sin(s)))⇒41sin(r)=28sin(a)  ((SQ)/(sin(a)))=((14)/(sin(r)))⇒SQ=((14sin(r))/(sin(a)))=14((28)/(41))=((392)/(41))
$$\mathrm{s}_{\mathrm{1}} =\mathrm{s}_{\mathrm{2}} =\mathrm{s} \\ $$$$\frac{\mathrm{TS}}{\mathrm{PR}}=\frac{\mathrm{QT}}{\mathrm{QP}}\Rightarrow\mathrm{TS}=\frac{\mathrm{41}}{\mathrm{3}} \\ $$$$\mathrm{a}=\angle\mathrm{QST}\:,\mathrm{r}=\angle\mathrm{QST}=\angle\mathrm{PRQ} \\ $$$$\frac{\mathrm{SQ}}{\mathrm{sin}\left(\mathrm{a}\right)}=\frac{\mathrm{14}}{\mathrm{sin}\left(\mathrm{R}\right)} \\ $$$$\frac{\mathrm{28}}{\mathrm{sin}\left(\mathrm{s}\right)}=\frac{\mathrm{ps}}{\mathrm{sin}\left(\mathrm{a}\right)} \\ $$$$\frac{\mathrm{PS}}{\mathrm{sin}\left(\mathrm{R}\right)}=\frac{\mathrm{41}}{\mathrm{sin}\left(\mathrm{s}\right)}\Rightarrow\mathrm{41sin}\left(\mathrm{r}\right)=\mathrm{28sin}\left(\mathrm{a}\right) \\ $$$$\frac{\mathrm{SQ}}{\mathrm{sin}\left(\mathrm{a}\right)}=\frac{\mathrm{14}}{\mathrm{sin}\left(\mathrm{r}\right)}\Rightarrow\mathrm{SQ}=\frac{\mathrm{14sin}\left(\mathrm{r}\right)}{\mathrm{sin}\left(\mathrm{a}\right)}=\mathrm{14}\frac{\mathrm{28}}{\mathrm{41}}=\frac{\mathrm{392}}{\mathrm{41}} \\ $$$$ \\ $$
