Accepted Solution

A:

Answer:y = 97Step-by-step explanation:Solve for z first.Consider the biggest triangle's angles: z, 42°, and 55°Total angle adds up to measure is 180°.z + 42 + 55 = 180z + 97 = 180z = 180 - 97z = 83°Now consider the line angle: y and zA line has an angle of 180°. y and z are considered supplementary angles (angles that add up to 180°).z = 83°So,y + z = 180y + 83 = 180y = 180 - 83y = 97
