    angle BCE = angle BCA + angle ACE

    Let's find angle BCA and angle ACE:

    angle ACE:

    Arc AEC = 180

    Arc CE + Arc AE = 180

    50 + Arc AE = 180

    Arc AE = 130

    Angle ACE = 1/2 * Arc AE

    Angle ACE = 1/2 * 130

    Angle ACE = 65

    angle BCA:

    AB = BC => ABC is a Equilateral triangle

    => angle BCA = 45

    angle BCE = 45° + 65°

    angle BCE = 110°
