If ( \theta ) is in the third quadrant and its reference angle is (35^\circ), what is the principal value of ( \theta )?यदि ( \theta ) तीसरे चतुर्थांश में है और उसका संदर्भ कोण (35^\circ) है तो ( \theta ) का मुख्य मान क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (215^\circ)(215^\circ)
In the third quadrant the principal angle is (180^\circ+35^\circ=215^\circ). Add or subtract the reference angle according to the quadrant.तीसरे चतुर्थांश में मुख्य कोण (180^\circ+35^\circ=215^\circ) होगा। चतुर्थांश के अनुसार संदर्भ कोण जोड़ें या घटाएं।
