m< 6 = m < 8 = 23 degrees ( m< 6 is vertically opposite to m<8)
m<5 = 180 - 23 =157 degrees ( angle on a straight line)
m < 7 = m < 5 = 157 degrees (m <7 and m < 5 are vertically opposite angles)
m < 1 = m < 5 = 157 degrees ( m < 1 is a corresponding angle to m < 5)
m < 4 = m < 8 = 23 degrees ( m < 4 and m < m < 8 are corresponding angles)
m < 3 = m < 5 = 157 degrees ( m < 3 and m < 5 are alternate angles)
m < 2 = m < 4 = 23 degrees ( m <
