Question

If 7tan=4 then (7sin A -3cos A )/7sin A +3cos A)

Answer 1

Answer:

1/7

hope it will help you.

Answer 2

Answer:

1/7

Explanation:

tan A = 4/7 = sin A/cos A

=> sin A = 4 and cos A = 7

=> 7sin A = 4*7 = 28 and 3cos A = 7*3 = 21

=> (7sin A - 3cos A )/(7sin A + 3cos A ) = (28 - 21)/(28 + 21)

=>7/49 = 1/7
