Use the given information to solve the triangle shown in the figure to the right. a =9.7, b = 12.5 b B DC What is the length of side c? c= (Round to the nearest tenth as needed.) What are the unknown angles? A= (Round to the nearest degree as needed.) B = (Round to the nearest degree as needed.)Find the trigonometric ratio by referring to the figure. sec B 10 6 8 sec B= (Simplify your answer. Type an integer or a fraction.)Explain why the range of the cosecant function is ( - co, - 1] U [1,co). The cosecant function, csc x, is the reciprocal of f(x) = The value of f(x) is always at least and no more than . If f(x) 0 , then csc x is less than - 1. less than or equal to - 1. greater than or equal to 1. undefined. between - 1 and 1. greater than 1.Use a graphing calculator set in radian mode to graph the function in the given domain and range. y = 6 sin xX, OSX$2, - 6sys6 Choose the correct graph below. O A. O B. O C. OD.Find the exact value without using a calculator. cSc 450 csc 450 = (Simplify your answer, including any radicals. Use integers or fractions for any numbers in the expression.)
