Question

Please solve this question its very argent

Answer 1

Let PQT and TQR be x.
and PRT and TRS be y.
In PQR ,
2x + QPR = 2y ( By exterior angle property) .....1
2x + QPR / 2 =y
In QTR,
x + QTR = y ( By exterior angle property) .........2

From 1 and 2 we have ,
2 x + QPR / 2 = x + QTR
QTR =1/2 QPR
Therefore, proved.
