Question

Draw BC that divides ABD

Answer 1

Answer:

Attached below is the missing figure

answer :  ∠ABD = ∠AbC  + ∠ CbD

Step-by-step explanation:

when Line BC is drawn to divide ∠ABD equally

solving each angle :

∠ABD  >  ∠AbC also angle

∠ABD  >  ∠ CbD

∴ ∠ABD = ∠AbC  + ∠ CbD

assuming ∠B = 60°

therefore ∠b = 60 / 30 = 30°
