[tex]QR^{2} [/tex] = [tex]PR^{2} [/tex] - [tex]QP^{2} [/tex]
= [tex]10^{2} [/tex] - [tex]8^{2} [/tex]
= 100 - 64
= 36
QR = [tex] \sqrt{36} [/tex]
= 6 cm
[tex]QS^{2} [/tex] = [tex]PS^{2} [/tex] - [tex]QP^{2} [/tex]
= [tex]17^{2} [/tex] - [tex]8^{2} [/tex]
= 289 - 64
= 225
QS = [tex] \sqrt{225} [/tex]
= 15 cm
RS = QS - QR
= 15 - 6
= 9 cm
