EXAMPLE 2 a. Given that find m 2. Find measures of a complement and a supplement 1 is a complement of 2 and m 1 = 68°, EXAMPLE 3 Find angle measures Sports When viewed from the side, the frame of a ball-return net forms a pair of supplementary angles with the ground. Find m BCE and m ECD. EXAMPLE 4 Identify angle pairs Identify all of the linear pairs and all of the vertical angles in the figure at the right. EXAMPLE 5 Find angle measures in a linear pair ALGEBRA Two angles form a linear pair. The measure of one angle is 5 times the measure of the other. Find the measure of each angle.
