The angle between VC and the plane is \(y\). It is not possible to use trigonometry to calculate the angle \(y\) because the length of another side is required. Pythagoras can be used to calculate ...

Draw the right-angled triangle OVC and label the sides. The angle between VC and the plane is \(y\). It is not possible to use trigonometry to calculate the angle \(y\) because the length of ...
