Answer 2

Answer:

3tanA =4

tanA = 4/3

As tan theta =

$\frac{perpendicular}{base}$

sin theta =

$\frac{perpendicular}{hypotenuse}$

cos theta =

$\frac{base}{hypotenuse}$

Hypotenuse =

$\sqrt{ {4}^{2} + {3}^{2} } = \sqrt{25} = 5$

So

sin theta = 3/5

cos theta = 4/5

which is the required ans
