Question

OB = 2,5OA AB = 18 AO =, OB

Answer 1

Объяснение:

ОВ=2,5ОА

Пусть х=ОА,

тогда ОВ=2,5х

АВ=ОА+ОВ

18=х+2,5х

18=3,5х

Х=18:3,5

Х=18:7/2=18×2/7=36/7

АО=36/7

ОВ=2,5×36/7=5/2×36/7=180/14=90/7

Answer 2

It seems like you're providing some information about points O, A, and B, but it's not entirely clear what you're asking. Are you looking for the value of AO or OB, or perhaps some other information related to these points and line segments? Please clarify your question, and I'd be happy to help.
