Use the given right triangle to find ratios, in reduced form, for sin A, cos A, and tan A. Triangle A B C has a right angle at angle C with legs B C = 8 and A C = 15, and hypotenuse A B = 17. 8 15 17 Enter the ratios in reduced form: sin A = nothing

Graph the system of inequalities presented here on your own paper, then use your graph to answer the following questions: y < 4x − 8 y is greater than or equal to negative 5 over 2 times x plus 5 part a: describe the graph of the system, including shading and the types of lines graphed. provide a description of the solution area. (6 points) part b: is the point (5, −8) included in the solution area for the system? justify your answer mathematically. (4 points)
