This is about angle theorems because angle theorems are theorems that help us to know the relationship between angles.
Option A: x = 105°
- We see that a transverse line cuts across two parallel lines DE and XY.
- Now, from transversal theorem of angles in Maths, we know that If a transverse line cuts across two parallel lines, then the alternate interior angles that are formed are congruent and therefore equal to each other.
- In this question, we see one of the angles as 105°. Therefore, x° will be congruent to it and thus; x = 105°
