Answer:

Step-by-step explanation:

∠AGB = ∠DGC    {Vertically opposite angles}

∠AGB = 90°

∠AGE + ∠AGB + ∠BGF = 180           {Angles on straight line}

30 + 90 + x = 180

120  + x       = 180

                x = 180 - 120

                x = 60°

Answer:

Solution,

Angle AGB=90°[Being vertically opposite angles]

Now we have,

30°+Angle AGB+x=180°

or,30°+90°+x=180°

or,x=180-30-90

Hence,x=60
