In a triangle ABC, ∠A = 70°, ∠B = 80° and D is the incenter of ΔABC, ∠ACB = 2x° and ∠BDC = y°. The values of x and y, respectively are:

Answer: Option B

∠C = 180 - (∠A + ∠B)
∠C = 180 - 150
2x = 30
x = 15°

∠BDC = 90° + $$\frac{1}{2}$$ ∠A
∠BDC = 90° + $$\frac{1}{2}$$ × 70°
∠BDC = 90° + 35°
∠BDC = 125°
So value of x and y are = 15°, 125°
