If (A=20^\circ 15') and (B=12^\circ 45'), what is (2A-B)?यदि (A=20^\circ 15') और (B=12^\circ 45'), तो (2A-B) का मान क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (27^\circ 45')(27^\circ 45')
(2A=40^\circ 30') and (40^\circ 30'-12^\circ 45'=27^\circ 45'). In exams, remember borrowing while subtracting minutes.(2A=40^\circ 30') और (40^\circ 30'-12^\circ 45'=27^\circ 45') है। परीक्षा में मिनट घटाते समय उधार लेना याद रखें।
