WebLet ABC be a triangle with angle bisector AD with D on line segment BC. If and , find AB and AC. Solution: By the angle bisector theorem, or . Plugging this into and solving for AC gives . We can plug this back in to find . In … WebJul 12, 2024 · Answer: BD = 5 Step-by-step explanation: ∠A = 60° Since AB = 20 = BC, Then ∠B = 60° resulting in a equilateral triangle with ∠C = 60°. Then dividing ∠DAE into half gives 4 = angles of 15° yielding each secition of BC being equal to 20/4 = 5. Do i don't think DE ≈ 9.28 cannot occur. Advertisement Advertisement
