Trigonometry: Labeling, Formulas, Solving

In this math worksheet, students label sides of right triangles as opposite, hypotenuse, and adjacent to the labeled angle. On the second page of the worksheet, students label the part of the right triangle marked with a question mark and identify the trig function they would use by the labeled parts. The third page asks students to solve for the marked part of the triangle using one of the three trig functions.
