Here's another example to work through. This time you need to draw two right-angled triangles to help you with your working. If \(\sin p = \frac{3}{5}\) and \(\tan q = \frac{5}{{12}}\) where \(0 ...

The adjacent side (\(a\)) is next to the angle in question (\(x\)). The trigonometric ratios for the angles 30°, 45° and 60° can be calculated using two special triangles. An equilateral ...
