Answer 2

Answer:

Two pairs of adjacent angles: (a°&c°) and (c°&b°)

Vertical Angle: (a°&b°)

b°+c°=180° (They lie on the same line, so they are supplementary)

a+b=280°

x+x=280° (Vertically opposite angles are equal. a=b=x)

2x=280°

x=280°/2

x=140°

Now, we now that b+c=180°

140°+c=180° (Put the value of b i.e. b=X=140°)

c=180°-140°

c=40°
