Answer:
e = 83°, f = 121°, g = 121° and h = 90°
Explanation:
See the attached diagram.
Since, GF ║ AB, and GB is the transverse line so, e = 83° {Alternate angles}
Now, e + f + 156° = 360°
⇒ 83° + f + 156° = 360°
⇒ f = 121°
Now, AB ║ CB and BC is the transverse line, so, f = g {Alternate angles}
⇒ g = 121°
Now, DF is perpendicular to CD and GF ║ CD, hence, DF is perpendicular to GF.
Hence, angle h = 90°.
Therefore, e = 83°, f = 121°, g = 121° and h = 90° (Answer)
