Calculate the angle QPR. Give the answer to one decimal place. Label the sides of the triangle \(o\), \(a\) and \(h\). Next choose the correct ratio from \(s^o_h~c^a_h~t^o_a\). In the triangle the ...
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' theorem can be used to ...
