1. Problem Description

We are given a triangle OABOAB with a line segment HKHK inside it such that HH lies on OAOA and KK lies on OBOB. We are given the lengths OH=9OH = 9 cm, HA=5HA = 5 cm, HK=6HK = 6 cm and AB=8AB = 8 cm. We need to calculate the lengths of OKOK and KBKB.

2. Solution Steps

Since we are given OH=9OH=9 cm and HA=5HA=5 cm, we can find the length of OAOA:
OA=OH+HA=9+5=14OA = OH + HA = 9 + 5 = 14 cm.
We will use similar triangles.
If OHKOAB\triangle OHK \sim \triangle OAB, then the ratios of corresponding sides are equal.
That is, OHOA=OKOB=HKAB\frac{OH}{OA} = \frac{OK}{OB} = \frac{HK}{AB}.
We are given OH=9OH = 9 cm, OA=14OA = 14 cm, HK=6HK = 6 cm and AB=8AB = 8 cm.
So we have 914=OKOB=68=34\frac{9}{14} = \frac{OK}{OB} = \frac{6}{8} = \frac{3}{4}.
Since OHOAHKAB\frac{OH}{OA} \ne \frac{HK}{AB}, OHK\triangle OHK is not similar to OAB\triangle OAB.
However, if OHK=OAB\angle OHK = \angle OAB, and OKH=OBA\angle OKH = \angle OBA, we still would not have enough information to find OKOK and KBKB without trigonometry, or other given information. The problem image does not clarify such information.
Assuming that triangles OHKOHK and OABOAB are similar then, OKOB=34\frac{OK}{OB} = \frac{3}{4}.
Let OK=3xOK = 3x for some xx. Then OB=4xOB = 4x.
We need to find OKOK and KBKB.
Since OB=OK+KBOB = OK + KB, we have 4x=3x+KB4x = 3x + KB, so KB=xKB = x.
Also OHOA=OKOB=HKAB\frac{OH}{OA} = \frac{OK}{OB} = \frac{HK}{AB}
914=OKOB=68=34\frac{9}{14} = \frac{OK}{OB} = \frac{6}{8} = \frac{3}{4} which is not possible. Therefore our initial assumption must be invalid.
From the image, it seems that OKH=90\angle OKH = 90^\circ although the image is not very clear. If OHKOAB\triangle OHK \sim \triangle OAB, then OAB=90\angle OAB = 90^{\circ}, which is not possible in a triangle. Therefore the triangles cannot be similar.
We will assume the problem actually has a typo and that HKHK is parallel to ABAB. If so, triangles OHKOHK and OABOAB are similar.
Then OHOA=OKOB=HKAB\frac{OH}{OA} = \frac{OK}{OB} = \frac{HK}{AB}
914=OKOB=68=34\frac{9}{14} = \frac{OK}{OB} = \frac{6}{8} = \frac{3}{4} is still inconsistent, therefore the image is not correctly drawn to scale.
The assumption that HK is parallel to AB is not accurate.
If we assume that the triangles are similar, then OHOA=OKOB=HKAB\frac{OH}{OA} = \frac{OK}{OB} = \frac{HK}{AB}.
914=OKOB=68\frac{9}{14} = \frac{OK}{OB} = \frac{6}{8}.
OKOB=34\frac{OK}{OB} = \frac{3}{4}
OB=43OKOB = \frac{4}{3} OK
KB=OBOK=43OKOK=13OKKB = OB - OK = \frac{4}{3}OK - OK = \frac{1}{3}OK
914=34\frac{9}{14} = \frac{3}{4} is incorrect. We are missing information.
Without any more information, we cannot solve for OKOK or KBKB.
However, if the question meant that the triangles are similar then.
Since HKAB=68=34\frac{HK}{AB} = \frac{6}{8} = \frac{3}{4}.
OHOA=914\frac{OH}{OA} = \frac{9}{14}.
We would need a new equation to solve for OKOK.

3. Final Answer

Without additional information or assumptions, such as HKHK is parallel to ABAB or that triangles OHKOHK and OABOAB are similar and OH/OA=HK/ABOH/OA = HK/AB, we cannot determine the values of OKOK and KBKB. We cannot use OH/OA=HK/AB=OK/OBOH/OA = HK/AB = OK/OB because 9/146/89/14 \neq 6/8. The question is flawed as it is presented.
