We can find an unknown angle in a right-angled triangle, as long as we know the lengths of two of its sides. The ladder leans against a wall as shown.

This online trigonometry calculator is used to find missing angles in a right-angled triangle. Simply enter two of the side lengths as listed in the diagram shown.

The initial set up for solving these problems will be the same as that for finding a missing side. To finish the problem, however, it will be necessary to use a calculator function referred to as an "inverse …
