very difficult question

[sunny sharma]

In triangle ABC angle B and angle C both are equal to 80 degree.points D and E on AC and AB respectively are such that angles DBC and ECB are 30 and 20 degree respectively then find the angle BDE

Please also tell us what grade home-work this is and give us some idea about the "triangle and angle theorems" that you can use.
