Answer:

180° (in place of blank)

Step-by-step explanation:

GIVEN :-

PROCEDURE :-

∠C & ∠D are linear pair. (∵ They lie on same line)

⇒ ∠C + ∠D = 180°

⇒ ∠C = 180° - 127°

In a triangle , sum of its all interior angles equals to 180° (which is also known as "Angle Sum Property). So,

∠A + ∠B + ∠C = 180°

⇒ 75° + ∠B + (180° - 127°) = 180°

⇒ ∠B = 180° - 75° - (180° - 127°)
