Right Triangle Using Trigonometric Ratios

What type of triangles do you use the trig ratios with?

Use inverse trig ratios (SOH CAH TOA) to solve for the missing angle

Solve for the missing angle

What is the length of side x?

We can use SOH-CAH-TOA for ​ ​ (a)  

Using trigonometric ratios, how can you find the measure of an angle in a right triangle if you know the lengths of the opposite side and the adjacent side?

In a right triangle, if one of the angles is $$30^\circ$$ and the hypotenuse is 10 units long, what is the length of the side opposite to the $$30^\circ$$ angle?

Solve for IR

Match the following

If you are given the opposite leg and hypotenuse, which trig ratio should you use?
(a)
