EXTRA CREDIT Solving Right Triangles 1. A vertical stone pillar stands on a slope that makes a 22 angle with the horizontal. At a time of the sun's rays pillar day when the angle of elevation of the sun is 62, A the stone pillar casts a shadow that is 20.5 meters D shadow long as measured along the slope. 20.5 m a. Find m/DEA. b. Find mZEDA. 620 220 c. Find mZDAE. Aside from the trigonometric functions, sine, cosine, and tangent, we can also use the functions cosecant, secant, and cotangent when describing the ratios of sides in a right triangle. The functions are defined as: Cosecant, denoted as csc 0 = - 1 hyp sin 8 opp Secant, denoted as sec 0 = 1 hyp cos 8 adj Cotangent, denoted as cot 0 = ad = tan e opp In Exercises 2-4, write the following trigonometric ratios for the triangle to the right. 2. csc 0 13 12 3. sec 0 A B 4. cot 8 In Exercises 5-7, find the measure of the acute angle. Round to the nearest tenth, if necessary. 6. sec 0 = 7. cot 0 = 15 5. csc 0 = 2 4 8. In right triangle RST, LS is the right angle, and sec T = 14. Find m/R . Round your answer to the nearest tenth
