Question

If cos theta + sin theta / sin theta - cos theta = 5/3 then find value of theta

Answer 1

Step-by-step explanation:

cos theta + sin theta /sin theta - cos theta =5/3.

cos theta +1/cos theta /1/cos theta - cos theta =5/3.

cos theta +1/cos theta =5/3

cos theta +sin theta =5/3. (1/cos theta,= sin theta)

cos theta /1 + 1/cos theta =5/3.

cos theta +1/cos theta =5/3. ( cross multi)

3 cos theta +3= 5 cos theta.

3 = 5 cos theta - 3 cos theta.

3= 2 cos theta.

3/2 = cos theta.

cos theta =1.5
