Question 132Asked in BPSC TRE 2.0 (2023) Mathematics Class 9-10

If PA and PB are two tangents to a circle with centre O such that ∠AOB = 110°, then ∠APB is equal toयदि PA और PB केन्द्र O वाले वृत्त की दो स्पर्श-रेखाएँ हैं, जैसे कि ∠AOB = 110° है, तो ∠APB बराबर है

यदि PA और PB केन्द्र O वाले वृत्त की दो स्पर्श-रेखाएँ हैं, जैसे कि ∠AOB = 110° है, तो ∠APB बराबर है
  1. A60°60°
  2. B70°70°
  3. C80°80°
  4. DMore than one of the aboveउपर्युक्त में से एक से अधिक
  5. ENone of the aboveउपर्युक्त में से कोई नहीं

Correct answer: (B) 70°70°

Explanation

In quadrilateral OAPB, ∠OAP = ∠OBP = 90°, so ∠APB = 180° - 110° = 70°.चतुर्भुज OAPB में ∠OAP = ∠OBP = 90°, अतः ∠APB = 180° − 110° = 70°।
