In the given figure, angle ABD = 110 degrees and angle ACE = 125 degrees. What is the value (in degrees) of angle BAC?
Show answer & explanation
Correct answer: B
Explanation
Given:
∠ABD = 110°, ∠ACE = 125°
Sum of angles on a straight line = 180°
Sum of angles in a triangle = 180°
∠ABC = 180° − 110° = 70°
∠ACB = 180° − 125° = 55°
∠BAC = 180° − (70° + 55°) = 55°
