Question

An equilateral TQR is drawn inside a
square PQRS. The value of PTS is??
1.75
2.90
3.120
4.150​

Answer 1

Answer:

4) 150

Step-by-step explanation:

<SRT = 90°- 60° = 30°

∴<RTS = 1/2 (180° - 30°) = 75°

∴<PTQ = <RTS = 75°

∴<PTS + <PTQ + <QTR + <RTS = 360°

=> <PTS + 75° + 60° + 75° = 360°

=><PTS = 360° - 210° = 150°

∴ The answer is 150°
