Question

Cos square theta + 5 sin theta cos theta is equal to 3 find tan theta​

Answer 1

Step-by-step explanation:

5 tan theta=4

So tan theta=4/5

therefore, sin theta/cos theta = 4/5

Hence we can say that,

sin theta= 4x , cos theta= 5x

So, (5 sin theta - 3 cos theta)/(5 sin theta+ 2 cos theta)

      = (20x-15x)/(20x+10x)

      = 5x/30x=1/6
