What are the principal angle and quadrant of (1245^\circ)?कोण (1245^\circ) का मुख्य कोण और चतुर्थांश कौन सा है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (165^\circ), second quadrant(165^\circ), दूसरा चतुर्थांश
(1245^\circ-1080^\circ=165^\circ), so the angle lies in the second quadrant. In exams, first subtract multiples of (360^\circ).(1245^\circ-1080^\circ=165^\circ), इसलिए कोण दूसरे चतुर्थांश में है। परीक्षा में पहले (360^\circ) के गुणज घटाएं।
