Your calculator can give you the answer to any trigonometric ratio you want. Say we want to find how long side ‘a’ is. What we can do is write a trigonometric ratio which has ‘a’ in it. To do this, we’re going to have to pick one of the angles (apart from the right angle) in the triangle. Let’s pick the 40° angle.

A trigonometric ratio is a ratio of two sides of a right triangle. We can use trigonometric ratios to relate the angles of a triangle to the lengths of the triangle’s sides. In a right triangle, three relationships exist which relate the angles of a triangle to the measures of its sides. The word . opposite
