The reference angle of an angle is (\frac{1}{4}) of a right angle and it lies in the second quadrant. What is the angle?किसी कोण का संदर्भ कोण समकोण का (\frac{1}{4}) है और वह द्वितीय चतुर्थांश में है। वह कोण क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (\frac{7\pi}{8})(\frac{7\pi}{8})
A right angle is (\frac{\pi}{2}) so the reference angle is (\frac{\pi}{8}). In the second quadrant the angle is (\frac{7\pi}{8}).समकोण (\frac{\pi}{2}) है इसलिए संदर्भ कोण (\frac{\pi}{8}) है। द्वितीय चतुर्थांश में कोण (\frac{7\pi}{8}) होगा।
