Answer:

PR = 15/2 units (OR) 7.5 units

Step-by-step explanation:

∵ triangle ABC is similar to triangle PQR

\frac{AB}{PQ} = \frac{BC}{QR} =\frac{AC}{PR}

(i)

\frac{AB}{PQ} = \frac{BC}{QR}

\frac{6}{PQ} =\frac{8}{6}

\frac{6}{PQ} =\frac{4}{3}

\frac{3}{PQ} =\frac{2}{3}

PQ = \frac{9}{2}

(ii)

\frac{AB}{PQ} =\frac{AC}{PR}

\frac{6}{9/2 } =\frac{10}{PR}

\frac{(6)(2)}{9} = \frac{10}{PR}

\frac{2}{3} = \frac{5}{PR}

PR = \frac{15}{2}
