If 3 tan theta =4 , prove that 5sin alpha - 3 cos alpha / 3 sin alpha + 3 cis alpha = 11/21

We have been given that . We are asked to prove that .

First of all, we will solve for tangent of alpha as:

Now, we will divide left side of our given equation by as:

We know that , so we will get:

Upon substituting , we will get:

Hence proved.
