Image 1 Use:

tan(angle) = opposite/adjacent

Image 2 Use:

cos(angle) = adjacent/hypotenuse

Image 3 Use:

a² + b² = c²

If you're given an angle and 1 side then you can use sin(), cos(), or tan() to solve for the other missing side.

If you're given two sides then you can use the pathagorean theorem, a² + b² = c², to solve for your missing side.
