Detailed Solution
Download Solution PDFপ্রদত্ত:
\(∠ ARS = 125^\circ\)
ধারণা:
একটি অর্ধবৃত্তে গঠিত কোণ একটি সমকোণ হয়।
একটি বৃত্তের একই অংশে গঠিত কোণগুলি পরিমাপের দিক থেকে সমান হবে।
গণনা:
B এবং R যুক্ত হয়ে BR গঠিত হয়েছে।
∠ARS + ∠ARP = 180° [রৈখিক যুগ্ম]
⇒ ∠ARP = 180° - 125° = 55°
∠ARB = 90° [অর্ধবৃত্তে গঠিত কোণ]
⇒ ∠ARP + ∠BRP = 90°
⇒ ∠BRP = 90° - 55° = 35°
∠BRP = ∠PAB = 35° [একই অংশে গঠিত কোণ]
∴ ∠PAB = 35°
