I need help working through this study guide. I am lost. Thanks.

8. Use the trigonometric ratios sine, cosine, and tangent to answer the following questions. Part I: Find the sine, cosine, and tangent ratios of 4X. (3 points) Y 13 Part II: Find the sine, cosine, and tangent ratios of 4 Y. (3 points) Y 13 10. cis a common factor. I 11. a2+.l12=c2 l 7. Find the exact value of each of the following. That is, no decimals are allowed, and no calculators are allowed. In each case, show your work and explain the steps you take to nd the value. Part I: sin 17\" . B A. Use the fact that there are 2 Jr radians in each circle to nd another angle, smaller than 211 , that is equivalent to 1T?\" . (1 point) B. Find the sine of the angle you found in part A.
