(20 1 1? Suzhou) as shown in the figure, it is known that △ABC is an equilateral triangle with an area of 3, △ABC∽△ADE, AB=2AD, ∠ Bad = 45, and AC and DE intersect at

∴S△ADES△ABC=AD2AB2，

AB = 2AD，S△ABC=3，

∴S△ADE=34，

As shown in the figure, in △EAF, the intersection point f is FH⊥AE, AE is in H,

Then ∠ AFH = 45, ∠ EFH = 30,

∴AH=HF，

Let AH=HF=x, then eh = xtan 30 = 33x.

∫S△ADE = 34，

Draw CM⊥AB from AB to m,

∫△ABC is an equilateral triangle with an area of 3.

∴ 12×AB×CM=3，

∠BCM=30，

AB=2k, BM=k, CM= praised and trampled. What's your comment on this answer?
