Answer
$\sin{A} = \frac{3}{5}
\\\cos{A} = \frac{4}{5}
\\\tan{A} = \frac{3}{4}$
Work Step by Step
RECALL:
In a right triangle,
$\sin{A} = \dfrac{\text{length of opposite side}}{\text{length of hypotenuse}}
\\\cos{A} = \dfrac{\text{length of adjacent side}}{\text{length of hypotenuse}}
\\\tan{A} = \dfrac{\text{length of opposite side}}{\text{length of adjacent side}}$
Use the formulas above to obtain:
$\sin{A} = \frac{3}{5}
\\\cos{A} = \frac{4}{5}
\\\tan{A} = \frac{3}{4}$
