Label the sides with their lengths and give the angles in radians. (See Watch, Read and Think 6.2: Standard Triangles) (a) Explain how to use similar and special triangles to find angles 0 and o in Triangle A in Figure 1. Give these angles in radians. (b) Explain how to use similar and special triangles to find angles o and S in Triangle B in Figure 1. Give these angles in radians. (c) Explain how to use a special triangle to find cos(#/6) and give the answer. (2) Find the length of side c in Triangle C in Figure 1. (3) Find the angle o in Triangle C in radians. (4) Find the length of side a in Triangle D in Figure 1. (5) Find the angle y in triangle D in radians. (6) Convert 21 degrees to radians. (7) Convert = radians to degrees. TASK 3: FUNCTIONS AND RELATIONS (1) Give the domain and range for the following functions: (a) y = (b) y = 23 V5-1 (2) Give an example of a value of a that shows that a + y = 49 is not a function, and explain why
