Answer 2

Answer:

given cos =0.6

then using

${sin}^{2} + { \cos}^{2} = 1$

now

${sin}^{2} = 1 - {0.6}^{2} \\ {sin}^{2} = 1 - 0.36 \\ {sin}^{2} =0.64 \\ sin = 0.8$

now ...

$tan = \frac{sin}{cos} = \frac{0.8}{0.6} = \frac{8}{6} = 1.33$

now putting these values in equation..

let LHS

5sin-3tan

$= 5 \times 0.8 - 3 \times 1.33 \\ = 4 - 3.99 \\ = 4 - 4(approx) \\ = 0 = rhs$

hence proved
