if cos theta = -1/2 and tan theta >0 show that 5tan theta + 4 sin theta/root 3 cos theta -3 sin theta is equal to 3

```							Dear student theta = 240 degree hence sin theta = sqrt(3) /2tan theta = sqrt(3) hence 5 tan theta + 4 sin theta = 5 sqrt(3) - 2 sqrt(3) = 3 sqrt(3) sqrt(3) cos theta – 3 sin theta = – sqrt3)/2 + 3 sqrt(3)/2 = sqrt(3) hence now dividing = 3

```							Dear student CosQ = 1/2 base = 1 hypotaneous = 2 perpendicular = rioot (3) tan Q = root(3)sinQ = root(3)/2 put in the equation LHS = [5root(3) + 2root(3)]/ [root(3)/2 - 3root(3)/2 ]LHS = 3 Which is equal to RHS
