Answer» ong>Answer: As we know that, ANGLES on the same segments are equal. therefore, ANGLE BDC = angle BAC ∆ABC is an equilateral triangle so, angle BAC = 60° hence, angle BDC = 60° quadrilateral BECD is a concyclic quadrilateral. therefore, angle BEC+ angle BDC = 180 or, angle BEC = 180-60 = 120° Hence, Required angle BDC and angle BEC are 60° and 120° respectively. |
