Answer:
Below in bold.
Step-by-step explanation:
Note that the lines q and m are parallel.
m < 1 = 180 - 110 = 70 degrees. ( adjacent angles)
m < 2 = 180 - 115 = 65 degrees ( adjacent angles)
m < 3 = m < 2 = 65 degrees ( lines q and m are parallel and 2 and 3 are corresponding angles).
m < 4 = 180 - 65 = 115 degrees (adjacent to < 3).
m < 5 = 180 - m < 1 - m < 3 = 180 - 70 - 65 = 180 - 135 = 45 degrees. ( angles in a triangle add up to 180 degrees).
m < 6 = m < 5 = 45 degrees ( q and m are parallel - alternate angles).
m < 7 =- m < 6 = 45 degrees ( opposite angles).
