Question

If 7tan =4then find value of 7sin theta - 3cos theta

Answer 1

Step-by-step explanation:

7 tan theta =4

7×sin theta/ cos theta =4

7 sin theta = 4 cos theta

sin theta = 4/7 cos theta

given ;

7 sin theta - 3 cos theta

7(4/7 cos theta )-3 cos theta

4 cos theta - 3 cos theta

= cos theta (ans)
