Question

If theta lies in the first quadrant and 5 tan theta = 4 then
( 5 sin theta - 3 cos theta )/( sin theta + 2cos theta )

Help me ​

Answer 1

Answer:

5tan theta =4

tan theta=4/5

now

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

divise by cos theta

(5tan theta -3) /(tan theta+2)

(5*4/5-3) /(4/5+2)

(4-3) /(4+10/2)

1/7
