Ans 6) ∠CAD + ∠ADB = 180° [Linear Pair]
So, ∠ADB = 120°
Now, In triangle, DAB
∠D + ∠A + ∠B = 180°
so, y = 20°
and, In triangle ABC
∠A+∠B+∠C = 180°
so, x = 180-130
x = 50°
So, ∠ADB = 120°
Now, In triangle, DAB
∠D + ∠A + ∠B = 180°
so, y = 20°
and, In triangle ABC
∠A+∠B+∠C = 180°
so, x = 180-130
x = 50°
fakesoul:
