Question

in the following figure,find angle YBC​

Answer 1

answer: ∠B = 60°

Step-by-step explanation:

Angle Sum Property of triangles = sum of all angles of a triangle = 180°

∠A = 180° - 110° (as they are a linear pair)

∠A = 70°

∠C = ∠DCE (as they are vertically opposite angles)

∠C = 50°

∴ ∠B = 180° - (∠A + ∠C)  (Angle Sum Property of triangles)

∠B = 180° - (70° + 50°)

∠B = 180° - 120°

∠B = 60°
