As shown in the figure, BD bisects ∠ ABC, be bisects ∠ ABC into two parts of 2:5, ∠ DBE = 27 ° and calculates the degree of ∠ ABC

As shown in the figure, BD bisects ∠ ABC, be bisects ∠ ABC into two parts of 2:5, ∠ DBE = 27 ° and calculates the degree of ∠ ABC

Let ∠ ABC = α, then ∠ abd = A2, ∠ Abe = 27 α ∫ DBE = ∠ abd - ∠ Abe ∫ a2-27 α = 27 ° and α = 126 ° A: ∠ ABC = 126 °
