For a right-angled triangle, follow these steps to calculate the length of a side ... adjacent (\(a\)) and \(x\) should be labelled as hypotenuse (\(h\)). The only trigonometric equation ...

For a right-angled triangle, follow these steps to calculate an angle \(Ɵ\), when ... the angle Ɵ and gives the answer to adjacent ÷ hypotenuse (in this example, 16/32). cos⁻¹ is the inverse ...
