here (x+3)°+(x+20)°+(x+7)° = 180°
=> (3x+30)° = 180°
=>3x° = 150°
=> x = 50
=> (3x+30)° = 180°
=>3x° = 150°
=> x = 50

since sum all angles given on a line (Co linear angles) =180'
=>angle EAD+angle dbc+angle CBF=180'
=>x+3+x+20+x+7=180'
=>3x+30=180'
=>3x=180-30'
=>3x=150
=>x=150/3
=>x=50'
=>angle EAD+angle dbc+angle CBF=180'
