In the figure given below, Ray PT is bisector of ∠QPR. If PQ = 5.6 cm, QT = 4 cm and TR = 5 cm, find the value of x .
उत्तर
Given: ray PT is bisector of ∠QPR.
PQ = 5.6 cm, QT = 4 cm and TR = 5 cm.
In a triangle, the angle bisector divides the side opposite to the angle in the ratio of the remaining sides.
`"QT"/"TR"="PQ"/"PR"`
`4/5=5.6/x`
`x=(5.6xx5)/4`
`x=28/4=7`
`PR=7cm`
