Question

Find the value of theta(theta less than 90°) if cos theta/1-sin theta+cos theta /1+sin theta=4​

Answer 1

Answer:

Find the value of theta(theta less than 90°) if cos theta/1-sin theta+cos theta /1+sin

Step-by-step explanation:

Cos theta/1-sin theta+cos theta/1+sin theta

cos theta (1+sin theta)+cos theta(1-sin theta)/1¹-sin²theta

cos theta+cos theta sin theta +cos theta-sin theta cos theta/1-sin² theta

cos theta+cos theta/cos² theta

2cos theta/cos²theta

2/cos theta=4

cos theta=1/2

theta=60° _____________(as cos 60°=1/2)
