Question

Angle ebd= (x+3)°,angle dbc=(x+20)°,angle cbf=(x+7)°

Answer 1

ANGLE EBD=(X+3)'

ANGLE CBF=(X+7)'

ANGLE DBC=(X+20)'

So, angle EBC=(X+17)'

BY QUESTION,

EBD+EBC+CBF=180'

X+3'+X+17'+X+7'=180'

Or,3X+27'=180'

Or,3X=180'-27'

Or,3x=153'

Or,x=51'

Answer 2

Step-by-step explanation:

x+3+x+20+x+7 =180°

3x+30=180°

3x=180°-30

3x=150°

x=50°

Therefore,x+3=53°

x+20=70°

x+7=57°
