Question

Angle ACD is an exterior angle of equilateral Triangle ABC. Find Angle ACD. With Method plz​

Answer 1

Answer:

it's simple

= exterior angle of triangle ABC ( X ) + angle ACD = 180°

= X + 60° ( all the angles of equilateral triangle is 60°) = 180°

= X = 180° - 60°

= X = 120°

hence , the exterior angle ACD measure 120°
