Question

9) in given ∆ABC, if AE = 96 cm, BO:OD=7:5
& BE: EC=3:4, then find OE?

a) 64 cm
b) 60 cm
c) 70 cm
d) 65 cm​

Answer 1

Answer:

take BO=7a,OD=5a

Draw EF||BD,where F is on side AC

NOW triangle BDC is similar to EFC

SO Using similarly EF =48a/7

NOW TRIANGLE AOD IS SIMILAR TO AEF AO/AE=OD/EF

substitute values and get AO =70 cm So OE=26 cm
