trigonometric ratios or formulas: Part I) Model Problems. Example 1: Consider right DEF pictured at right. We know one acute angle and one side, and our goal is to determine the length of the unknown side x. Step 1: Place your finger on the 38° angle (the acute angle), and then. label the three sides: the hypotenuse. is always the longest side ...
