∫CB∥OA，∠COA=90，
And CB=3, ∴OG=3,
∴GA=OA-OG=6-3=3，
And BG⊥x axis,
∴ In the right triangle AGB,
BG2=AB2-GA2=(35)2-32=36，
∴BG=6，
Then according to Pythagorean theorem:
OB=35，
From the known OE=2BE:
OE=25，BE=5，
By the known BG⊥x axis:
OC=BG=6，
∴OCOE=625=355，
OBOD=355 was praised and trampled. What is your evaluation of this answer?
