Question

Точка C середина ab точка o середина AC найдите ab, если OB =1,5см

Answer 1

Ответ:

2 см

Объяснение:

OB=$\frac{3}{4}$ AB

3*AB=4*OB

AB=$\frac{4}{3}$ OB=2 см

Answer 2

To find the length of AB, we can use the fact that point O is the midpoint of AC. Let's denote the length of AB as x.

Since O is the midpoint of AC, we can say that AO = OC. Given that OB = 1.5 cm, we can write the equation:

AO + OB = AB + OC

Since AO = OC and OB = 1.5 cm, we can substitute these values:

AO + 1.5 cm = AB + AO

Simplifying the equation, we find:

1.5 cm = AB

Therefore, the length of AB is 1.5 cm.
