I've always wondered… how high is the top of my barn from the lower side?

This telephone pole is the tallest one in my neighborhood. How tall do you think it is?

After successfully completing this learning module, students will be able to:

Use right triangles to evaluate trigonometric functions.
Find function values for $30° (\frac{π}{6}), 45° (\frac{π}{4}),$ and $60° (\frac{π}{3}) .$
Use equal cofunctions of complementary angles.
Use the definitions of trigonometric functions of any angle.
Use right-triangle trigonometry to solve applied problems, like the two problems posed above.

Introduction to this module:

In this module, we will examine the trigonometric functions that you might remember from Geometry class: sine, cosine, and tangent, as well as their reciprocals: cosecant, secant, and cotangent. We will also solve some problems using right triangle trigonometry.

To meet the learning outcomes in this module, students are expected to complete the following:

Reading by Section Name	Suggested Problems
Using Right Triangles to Evaluate Trigonometric Functions	17-28
Using Equal Cofunctions of Complements	6-9
