Given the inequality:
$$\sin{\left(x \right)} + \sqrt{3} \cos{\left(x \right)} > \sqrt{2}$$
To solve this inequality, we must first solve the corresponding equation:
$$\sin{\left(x \right)} + \sqrt{3} \cos{\left(x \right)} = \sqrt{2}$$
Solve:
$$x_{1} = 2 \operatorname{atan}{\left(\frac{1 - \sqrt{2}}{\sqrt{2} + \sqrt{3}} \right)}$$
$$x_{2} = 2 \operatorname{atan}{\left(\frac{1 + \sqrt{2}}{\sqrt{2} + \sqrt{3}} \right)}$$
$$x_{1} = 2 \operatorname{atan}{\left(\frac{1 - \sqrt{2}}{\sqrt{2} + \sqrt{3}} \right)}$$
$$x_{2} = 2 \operatorname{atan}{\left(\frac{1 + \sqrt{2}}{\sqrt{2} + \sqrt{3}} \right)}$$
This roots
$$x_{1} = 2 \operatorname{atan}{\left(\frac{1 - \sqrt{2}}{\sqrt{2} + \sqrt{3}} \right)}$$
$$x_{2} = 2 \operatorname{atan}{\left(\frac{1 + \sqrt{2}}{\sqrt{2} + \sqrt{3}} \right)}$$
is the points with change the sign of the inequality expression.
First define with the sign to the leftmost point:
$$x_{0} < x_{1}$$
For example, let's take the point
$$x_{0} = x_{1} - \frac{1}{10}$$
=
$$2 \operatorname{atan}{\left(\frac{1 - \sqrt{2}}{\sqrt{2} + \sqrt{3}} \right)} - \frac{1}{10}$$
=
$$2 \operatorname{atan}{\left(\frac{1 - \sqrt{2}}{\sqrt{2} + \sqrt{3}} \right)} - \frac{1}{10}$$
substitute to the expression
$$\sin{\left(x \right)} + \sqrt{3} \cos{\left(x \right)} > \sqrt{2}$$
$$\sin{\left(2 \operatorname{atan}{\left(\frac{1 - \sqrt{2}}{\sqrt{2} + \sqrt{3}} \right)} - \frac{1}{10} \right)} + \sqrt{3} \cos{\left(2 \operatorname{atan}{\left(\frac{1 - \sqrt{2}}{\sqrt{2} + \sqrt{3}} \right)} - \frac{1}{10} \right)} > \sqrt{2}$$

one of the solutions of our inequality is:
$$x > 2 \operatorname{atan}{\left(\frac{1 - \sqrt{2}}{\sqrt{2} + \sqrt{3}} \right)} \wedge x < 2 \operatorname{atan}{\left(\frac{1 + \sqrt{2}}{\sqrt{2} + \sqrt{3}} \right)}$$
