In this lesson, we will learn how to find a missing angle in a right triangle using the appropriate trigonometric function given two side lengths.

Students will be able to

label the sides and angle of a right triangle,
find an unknown angle measure in a right triangle (given a figure) using the sine, cosine, and tangent ratios and their inverse functions,
draw a figure for a question and use it to find an unknown angle in a right triangle,
interpret and solve real-life and applied problems using right triangle trigonometry.
