In the figure, (bigtriangleup)PQT is isosceles. PQ = QT, SRQ = 35o, TPQ = 20o…

Correct Answer: Option C

Explanation

Given (bigtriangleup) isosceles PQ = QT, SRQ = 35^o
TPQ = 20^o
PQR = is a straight line
Since PQ = QT, angle P = angle T = 20^o
Angle PQR = 180^o – (20 + 20) = 140^o
TQR = 180^o – 140^o = 40^o
QSR = 180^o – (40 + 35)^o = 105^o
TSR = 180^o – 105^o
= 75^o
