# High School Math : Applying Trigonometric Functions

## Example Questions

### Example Question #1 : Triangles In this figure, side  , and . What is the value of angle ?    Undefined Explanation:

Since , we know we are working with a right triangle.

That means that .

In this problem, that would be: Plug in our given values:    ### Example Question #2 : Triangles

Let ABC be a right triangle with sides = 3 inches, = 4 inches, and = 5 inches. In degrees, what is the where is the angle opposite of side ?      Explanation: We are looking for . Remember the definition of in a right triangle is the length of the opposite side divided by the length of the hypotenuse.

So therefore, without figuring out we can find ### Example Question #5 : Graphing The Sine And Cosine Functions In this figure, if angle , side , and side , what is the measure of angle ?   Undefined  Explanation:

Since , we know we are working with a right triangle.

That means that .

In this problem, that would be: Plug in our given values:
