If θ lies in the fourth quadrant and its reference angle is 22°, what is its principal angle, measured between 0° and 360°?यदि θ चौथे चतुर्थांश में है और उसका संदर्भ कोण 22° है, तो 0° और 360° के बीच उसका मुख्य कोण क्या होगा?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: 338°338°
In the fourth quadrant, the principal angle is 360° minus the reference angle. Thus θ = 360° − 22° = 338°.चौथे चतुर्थांश में मुख्य कोण 360° में से संदर्भ कोण घटाकर मिलता है। इसलिए θ = 360° − 22° = 338°।
