Question

if 5 tan theta=4 find 8 sin theta - 3cos theta /8sin theta + 2cos theta

Answer 1

Answer 2

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
