In the given figure, angle ABC = 40 degrees and angle BCA = 65 degrees. What is the value (in degrees) of angle ACD?
Show answer & explanation
Correct answer: B
Explanation
Given:
∠ABC = 40°, ∠BCA = 65°
According to the formulas:
Sum of angles in a triangle = 180°
Sum of angles on a straight line = 180°
∠BAC = 180° − (40° + 65°) = 75°
∠ACD = 180° − 65° = 115°
