Answer:
angle SQT = 60°
Step-by-step explanation:
angle PRT + RPT + RTP = 180°
40° + 95° + angle RTP= 180°
angle RTP = 180°-135°
angle RTP = 45°
angle STQ = angle RTP =45°(vertically opposite angles)
Using angle sum property ∆ STQ
angle STQ+ SQT +QST
45°+ SQT + 75° = 180°
angle SQT = 180° - 120°
angle SQT = 60 °
