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.
