In the given figure, angle ABC = 70 degrees. Angle AEF = 50 degrees. Angle CDE = 45 degrees. What is the value (in degrees) of angle ACD?
Show answer & explanation
Correct answer: C
Explanation
Given:
∠ABC = 70°, ∠AEF = 50°, ∠CDE = 45°
Formula:
Sum of angles on a straight line = 180°
∠ACD = 180° − (50° + 45°)
= 180° − 95°
= 85°
