Point b ∈ ac. find the length of segments ab and bc if ac = 20 cm and: ab: bc = 3: 7

will mark brainliestt i need answer asap

Length of AB  = 6 cm

Length of the segment BC =  14 cm

Step-by-step explanation:

Here, B is a point on a segment AC.

AB : BC = 3:7

Length of the segment AC = 20 cm

Now, let the common ratio between the segment is x.

So, the length of AB = 3 x , and Length of BC = 7 x

Now, AB + BC = AC

⇒  3x + 7x = 20

or, 10 x = 20

or, x = 2

Hence, the length of AB = 3 x = 3 x 2 = 6 cm

and the length of the segment BC = 7x =  7 x 2 =  14 cm

i believe so, according to my "strange" way of figuring out weird math problems like this.

this cant be answered without the graph. you may need to add it.
