Question

PLEASE TELL ME THE ANSWER OF THIS QUESTION??

Answer 1

in triangle QTR , TRS is an extirior angle
 TQR + QTR = TRS 
QTR = TRS - TQR  (eq,1)

in triangle QPR,PRS is an extirior angle 
QPR + 2 TQR =  2TRS   ( as QT and RT are angle bisectors)
QPR = 2(TRS - TQR)
QPR = 2 QTR (  e\by eq.1)

QTR = 1/2 QPR

hence proved 

hope i helped

Answer 2

It seems hard
anyone know how to do it
