solve and tell me how

Answer 1

Hi

Here is ur answer

5 tanα = 4

tanα = 4/5

since, sinα/cosα = tanα

sinα = 4

cos α = 5

Then substitute this in the given equation,

= 5sinα - 3cosα / 5sinα + 2cosα

= 5 × 4 - 3 × 5 / 5×4 + 2×5

= 20 - 15 / 20 + 10

= 5 / 30

= 1 /6

Therefore, the answer is option (A) .
