WebSep 22, 2024 · This is the angle outside the triangle because the direction B C → is pointing relative to A B →, and so, we should find the supplementary angle that is: β = 180 ∘ − 126.5 ∘ = 53.5 ∘ Let γ be the angle between A C → and B C →. Since the sum of the angles of a triangle is 180 ∘, so: α + β + γ = 180 ∘ 97.67 ∘ + 53.5 ∘ + γ = 180 ∘ 151.17 ∘ + γ = 180 ∘ WebWe know that BD is the angle bisector of angle ABC which means angle ABD = angle CBD. Now, CF is parallel to AB and the transversal is BF. So we get angle ABF = angle BFC ( alternate interior angles are equal). But we already know angle ABD i.e. same as angle ABF = angle CBD which means angle BFC = angle CBD.
