☺ Hello mate__ ❤
◾◾here is your answer...
Solution:
∠SPR+∠QPR=180° (Linear Pair)
⇒∠QPR=180°−∠SPR=180°−135°=45°
∠PQT=∠QPR+∠PRQ
(If a side of a triangle is produced, then the exterior angle is equal to the sum of two interior opposite angles.)
⇒110°=45°+∠PRQ
⇒∠PRQ=110°−45°=65°
I hope, this will help you.
Thank you______❤

110° - 180° = X (linear pair)
70° = X
Now, 180° - 135° = y (linear pair)
45° = y
Then
X + Y + Z = 180 (angle sum property)
70° + 45° - Z = 180
115 + Z = 180
Z = 180 - 115
Z = 65°
