9. If tan 6 = cot(30° + O), theo 8 = |
|
Answer» answer-30 Tan theta = cot (30 + theta)i.e. tan theta = tan { 90 – (30 + theta)} [ Because, tan theta = cot( 90 – theta)]i.e. tan theta = tan ( 90 – 30 –theta )i.e. theta = 60 – thetai.e. theta + theta = 60i.e. 2 theta = 60i.e. theta = 60 / 2i.e.theta 30° theta is 30 degreeit is the right answer 30 is the correct answer 30 is a good answer. ok theta =30° for this question 30 degrees is the correct answer 30 डिग्री इसका सही उत्तर है |
