It may be necessary to use Pythagoras' theorem and trigonometry to solve a problem ... The angle between AF and the plane is \(x\). Use \(\sin{x} = \frac{o}{h}\) \(\sin{x} ...

Let’s look at how to use trigonometric identities to calculate missing sides. \({sin~θ} = \frac {opposite} {hypotenuse}\) \({cos~θ} = \frac {adjacent} {hypotenuse ...
