Pythagoras’ theorem can also be used to find the length of another side of a triangle using the hypotenuse. The square on the hypotenuse subtracted by the square on another side is equal to the ...

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