प्रश्न
In the given figure, ∠Q = 90°, PS is a median om QR from P, and RT divides PQ in the ratio 1 : 2. Find: `("tan" ∠"PSQ")/("tan"∠"PRQ")`
उत्तर
As PS is the median on QR from P.
∴ QS = SR
⇒ QR = 2QS
and RT divides PQ in the ratio 1 : 2
∴ QT = x and PT = 2x
⇒ PQ = 3x
`("tan" ∠"PSQ")/("tan"∠"PRQ")`
= `("PQ"/"QS")/("PQ"/"QR")`
= `"PQ"/"QS" xx "QR"/"PQ"`
= `(2"QS")/("QS")`
= 2.
