A) 25 units
B) 12 units
C) 15 units
D) Can't be determined
Correct Answer: C
Solution :
In \[\Delta PQS.\] \[P{{S}^{2}}=P{{Q}^{2}}+Q{{S}^{2}}\] \[{{17}^{2}}={{8}^{2}}+Q{{S}^{2}}\]or \[Q{{S}^{2}}=289-64\] \[\Rightarrow \] \[Q{{S}^{2}}=225\text{ }\Rightarrow \text{ }QS=15\] from given conditions, \[RQ=OS\] (By CPCT) \[(\because \,\Delta PQR=\Delta PQS)\] \[\therefore \] \[QR=15\] units.You need to login to perform this action.
