$\sin\alpha=\frac{\sqrt3}{\sqrt5}$ $\sin\beta=\frac{\sqrt2}{\sqrt5}$

Work Step by Step

Using Pythagorean Theorem to find $c$. $c=\sqrt {\sqrt2^{2}+\sqrt3^{2}}$ $c=\sqrt {2 + 3}$ $c=\sqrt {5}$ $\sin\alpha=\frac{opposite}{hypotenuse}=\frac{\sqrt3}{c}=\frac{\sqrt3}{\sqrt5}$ $\sin\beta=\frac{opposite}{hypotenuse}=\frac{\sqrt2}{c}=\frac{\sqrt2}{\sqrt5}$
