How to set up trig ratios with a right triangle.
The video demonstrates how to set up a trig function in order to find missing length and angles of a right triangle.
Follow these steps to set up trig functions properly.
The first step is to find the reference angle.
Next, label the opposite,adjacent,hypotenuse sides of the right triangle.
Finally, decide which trig function to use and then set it up.
The trig functions used in this video are:
Sine=Opposite over hypotenuse
Cosine=Adjacent over hypotenuse
Tangent= Opposite over adjacent
