Question

5tanA = 3 then. 5 sinA - 3 cos A / 4sin A + 3 cos A

Answer 1

Step-by-step explanation:

Given

5 tanA = 3

tanA = 3/5

Now

5 sinA - 3 cosA / 4 sin A + 3 cosA

(dividing numerator and denominator by cosA you will get)

5 tanA - 3/ 4 tan A + 3

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

3-3/ 12/5+3

0/ 12+15/5

0/ 17/5

0

because when we divide or multiply with any number with zero you will always get zero

So,

5 sinA - 3 cosA/ 4 sinA + 3 cosA = 0
