In the given figure, x = 30°. What's the property of parallel lines used to find x? Question 6 options: A) Angles at the same side of the transversal are supplementary. B) Alternate interior angles are congruent. C) Alternate exterior angles are congruent. D) Corresponding angles are congruent.

Option (C)

Step-by-step explanation:

Option A.

"Angles at the same side of the transversal are supplementary".

But the angles given are not on the same side of the transversal.

Option B.

"Alternate interior angle are congruent"

These angles are not the interior angles.

Option C.

"Alternate exterior angles are congruent"

Both the angles are alternate and exterior angles.

Therefore, Option (C) is the correct option.

Option D.

"Corresponding angles are congruent"

These angles are not the corresponding angles.

x is variable or an unknown value to find

example:

2x = 5 which means x = 3
