Value of x is 20°
Step-by-step explanation:
By construction draw a line EF passing through Angle O
Now,
=> Angle DCO = 60° = Angle FOC...
(alternate interior Angles)
=> As we know that the sum of all the angles around a point is equal to 360°.....
280° + 60° + Angle BOF = 360°
Angle BOF = 360° - 340°
Angle BOF = 20°
=> Angle BOF = 20° = Angle ABO
=> Angle BOF = 20° = x ....
(alt. int. Angles)
