abcd is a rectangle. If measure angle bac=30 find the measure of angle dbc

its not that hard pls answer

Ummh 60° ??
Did you not make a diagram?
The answer would have been obvious. 
yupp i do know that answer is 60 but i need to write down .. with explanation properly

got the explanation xD

Ask yourself
"how did I know it was 60° ? " and that becomes your explanation .
