Question

ABCD is a trapezium such that
that BC/IAD
and AB= 4m. If the diagonals AC
and BD intersect at o such that
Ao/Oc = DO/OB = 1/2, then BC.​

Answer 1

Answer:

Given BC parallel to AD,andAD=4

Let BC=m

Let ∠AOD=x,⇒∠COB=x

Let ∠OAD=y,⇒∠OCB=y

Let CO=2a,⇒OA=1a

⇒ΔOAD,andΔOCB are similar,

⇒OAAD=OCCB

⇒1a4=2am

⇒m=8

Hence, BC=m=8

Answer 2

BC=8m is the correct answer
