Answer 1

I'll make it simple for you to understand. Change your perspective.

∠EGB is supposedly 180°

∠EGF + ∠AGF + ∠AGB = 180°

60° + 90° + ∠AGB = 180°

150° + ∠AGB = 180°

∠AGB = 180° - 150°

∠AGB = 30°

Hope this helps you

Answer 2

Answer:

see explanation

Step-by-step explanation:

∠BGC = ∠EGF = 60° ( vertical angles )

∠FGC = 180° ( straight angle ) and

∠AGF + ∠AGB + ∠BGC = ∠FGC = 180° ← substitute values

90 + ∠AGB + 60 = 180, that is

150 + ∠AGB = 180 ( subtract 150 from both sides )

∠AGB = 30°
