In parts (a) and (b) of the following figures, relationships among marked angles are given below the figure. Find the measure of the marked angles. In part (c), find only the measure of ZBOC and tell why the exact values of x and y cannot be determined. a. m(ZAOB) = and m(_COD) =] C B ID X O m(ZAOB) = =m(_COD) b. m(ZBOC) = \\ and m(ZAOB) = X A m(ZAOB) is 30 less than 4m(ZBOC) c. m(ZBOC) = Explain why exact values of x and y cannot be determined. The exact values of x and y cannot be determined, because the figure only gives enough information to find the of x and y precisely. To find x and y, more information about the relationship between x and y, or a value such as would be required
