60° + a = 180° (Co - interior angles)
a = 180° - 60°
a = 120°
a = c = 120° (Alternate angles)
Therefore c = 120°
c = b = 120° (Vertically Opposite Angles)
Therefore b = 120°
c + d = 180° (Linear Pair)
120° + d = 180°
d = 180° - 120°
d = 60°
Therefore a = 120°, b = 120°, c = 120° and d = 60°
Hope it helps :)
