Answer:
x = 7
Explanation:
corresponding interior angles are the angles which are formed in matching corners or corresponding corners with the transversal when two parallel lines are intersected by any other line
one is an obtuse and one is an acute angle in which sum up to 180°
(120°) + (7x + 11) = 180°
120° + 7x + 11 = 180°
131° + 7x = 180°
131° - 131° + 7x = 180° - 131°
7x = 49°
7x/7 = 49°/7
x = 7°
plug x in to check:
7(7) + 11 = 49 + 11 = 60
