Question

plz answr this question​

Answer 1

Answer:

Qtr=1/2qpr

Step-by-step explanation:

In triangle QPR

QPR+PQR=PRS

QPR+2X=2Y

QPR=2Y-2X

QPR=2(Y-X) (1)

IN TRIANGLE QTR

YQR+QTR=TRS

X+QTR=Y

QTR=Y-X (2)

FROM 1 AND2

QTR=2(Y-X)

QPR=2QTR

QTR=1/2QPR

PLEASE MARK IT AS A BRAINLIST

Answer 2

Answer:

Let angle QPR=x

Angle PQR=y

Angle PRQ=w

Angle PRS=z

Angle T=u

In triangle PQR

x+y+w=180(asp)--------(1)

In triangle QTR

w+z/2+u+y/2=180(asp)(z/2 cause T is the bisector) - - - - - - - - (2)

Angle Z=x+y(exterior angle property.)---------(4)

W+Z=180(linear pair)-----------(5)
