Question
The internal bisector of ∆ABC at ∠A cuts BC on D and
cuts the circumcircle at E. If DE = 6cm, AC = 8cm and AD = 10 cm, then find the length of AB?Solution
Join EC, From the diagram, AE = AD + DE AE = 10 + 6 = 16 cm ∠ABC = ∠ CEA (Similar Chord Theorem, In, ∆ADB and ∆AEC, (AB )/(AE )=(AD )/(AC ) (Similar triangle) (AB )/(16 )=(10 )/(8 ) AB = 20 cm
