# PROBLEM SOLVING LESSON 8-2 TRIGONOMETRIC RATIOS

Given the lengths of two sides of a triangle and the measure of the included angle, the area of the triangle can be found. By the AA Similarity Postulate, a right triangle with a given acute angle is similar to every other right triangle with that same acute angle measure. Round to the nearest hundredth. Be sure your calculator is in degree mode, not radian mode.
