Answer:
x = 11°
Explanation:
Since m and n are parallel, we know that the two angles given are consecutive interior angles (pairs of angles on the same side of a transversal between two parallel lines), which means that they are supplementary angles (they add up to 180°.
To find x, we have to turn this into an equation and then isolate x:
(6x - 13) + 127 = 180
Simplify
6x + 114 = 180
Subtract 114 from both sides
6x = 66
Divide both sides by 6
x = 11
