Answer
x = 7°
Step-by-step explanation
To solve this, we need to first describe corresponding angles.
Corresponding angles are angles that occupy similar positions on two parallel lines connected by another straight line (transversal line). As long as two parallel lines are involved, we know that corresponding angles are equal to each other.
From the image attached, 74° and (9x + 11)° are corresponding angles and are equal to each other
9x + 11° = 74°
9x = 74° - 11°
9x = 63°
Divide both sides by 9
(9x/9) = (63°/9)
x = 7°
