S O L U T I O N :
★ It is given that,
➽ AB || CD and EF CD
➽ ∠GED = 126º
➽ ∠GEF + ∠FED = 126º
➽ ∠GEF + 90º = 126º
➽ ∠GEF = 36º
➽ As ∠AGE and ∠GED are alternate interior angles.
➽ ∠AGE = ∠GED = 126º
➽ However, ∠AGE + ∠FGE = 180º (Linear pair)
➽ 126º + ∠FGE = 180º
➽ ∠FGE = 180º − 126º = 54º
★ Hence, ∠AGE = 126º, ∠GEF = 36º, ∠FGE = 54º ★
