math tutorials > calculating sides of a triangle using trig ratios

## Solving trig ratios - what you will need:

To solve trigonometric ratios you will need a **scientific
calculator**.
Depending on whether you have a **Direct Algebra Logic
(DAL) calculator** or not, the order you key in the calculation may vary. Experiment until
you get the results shown here.

## Steps

- Label the sides (o, a, h)
- Identify which trig. ratio uses these sides.
- Calculate the side.
