Answer 2

Answer:

Step-by-step explanation:

Given, ∠A + ∠B = 125° .........(i)

∠B + ∠C = 150°

In ΔABC,

∠A + ∠B + ∠C = 180°

Substituting the value of equation (i) in (ii)

(125°) + ∠C = 180°

∠C = 180 - 125

∠C = 55°

(∠B + ∠C) = 150°

∠B + 55 = 150

∠B = 95°

(∠A + ∠B) = 125°

∠A + 95 = 125

∠A = 30°

∴∠A = 30°

  ∠B = 95°

  ∠C = 55°
