If M and N are parallel and angle 1 is 135°, what is the sum of angle 6 and angle 8?%0D%0A%0D%0A(1 point)%0D%0A$$°%0D%0ACheck Answer
Since M and N are parallel, angle 1 and angle 8 are corresponding angles and have the same measure. So, angle 8 = 135°.
Angle 6 is a corresponding angle to angle 1. Since angle 1 = 135°, angle 6 also has a measure of 135°.
Therefore, the sum of angle 6 and angle 8 is 135° + 135° = 270°.
