Answer:
See the explanation part.
Step-by-step explanation:
2. a = 28° {Since they are corresponding angles}
d + 28° = 180°, ⇒ d = 152° {Supplementary angles}
b = d = 152°
c = a = 28°
3. a + 120° = 180°, ⇒ a = 60°
a = b = 60° {Alternate angles)
b + c = 180°, ⇒ c = 180° - 60° = 120°
d = a = 60° {Corresponding angles}
e = 110° {Opposite angles}
e + f = 180°{Supplementary angles)
⇒ f = 180° - 110° = 70°
a + g + f = 180° {They form a triangle}
⇒ g = 180° - a - f = 180° - 60° - 70° = 50° (Answer)
