Question

please answer the question below

Answer 1

Answer:

angle SQT is 90°

Hope you got it

Answer 2

Step-by-step explanation:

In ∆RPT,

<PRT + <RPT + <RTP = 180°

50° + 100° + <RTP = 180°

150° + <RTP = 180°

<RTP = 180° - 150°

---••• <RTP = 30°

---••• <RTP = <STQ = 30° ( Vertically Opposite Angles are equal)

In ∆SQT,

<QST + <SQT + <STQ = 180°

60° + <SQT + 30° = 180°

90° + <SQT = 180°

<SQT = 180° - 90°

---••• <SQT = 90°

Therefore, <SQT = 90°

I hope this helps you!
