GCSE Maths Practice: trigonometry

\( \begin{array}{l}\text{Which formulae could be used to find a missing side in a right-angled triangle?}\end{array} \)

Select all correct options:

\( \sin \theta = \frac{\text{opposite}}{\text{hypotenuse}} \) \( \cos \theta = \frac{\text{adjacent}}{\text{hypotenuse}} \) \( \tan \theta = \frac{\text{adjacent}}{\text{hypotenuse}} \) \( \tan \theta = \frac{\text{opposite}}{\text{adjacent}} \)
