In the given figure, AB is parallel to CD. Angle ABE = 80 degrees and angle BED = 125 degrees. What is the value (in degrees) of angle CDE?
Figure for question 13

Show answer & explanation

Correct answer: C

Explanation

Given:

AB ∥ CD

∠ABE = 80°

∠BED = 125°

Alternate interior angles formed by parallel lines are equal.

Sum of angles:

AB ∥ CD ⇒ ∠BEF = ∠ABE = 80°

∠BED = 125° ⇒ ​​∠FED = 125 − 80 = 45°

EF ∥ CD ⇒ ∠CDE = ∠FED = 45°
