Work out the size of EBC=

 140°

Step-by-step explanation:

∠C = 40°

BC = unknown  ⇒ ∠D = x

CD = BC            ⇒ ∠B = ∠D = x

Triangle Sum Theorem states: ΔBCD = ∠B + ∠C + ∠D = 180°

                                                                   x  +  40° +  x  = 180°

                                                                                    2x  = 140°

                                                                                       x = 70°

Given: ∠EBD ≡ ∠CBD    

            ∠EBD = 70°

Angle Sum Theorem: ∠EBC = ∠EBD + ∠CBD    

                                               =     70°  +   70°

                                               =         140°
