Question

2sec theta +3tan theta =7 find theta

Answer 1

Thank you for asking this question. Here is your answer:

First of all we will solve this:

2 sec theta + 3 tan theta will be equal to 7

2(1/cos theta)+3(sin theta/ cos theta) equal to 7

(2 + 3 sin theta)/cos theta equal to 7

2 + 3 sin theta will be equal to 7 cos theta

cos theta will be equal to (2 + 3 sin theta)/7
