I did not get the question can you explain it clearly?

Answer 2

Answer:

(i)OA = 5.6cm.

(ii)DO = 4 cm.

Step-by-step explanation:

Given Problem:

In the given figure, AOAB - LOCD. If AB = 8 cm, BO = 6.4 cm,

OC = 3.5 cm and CD = 5 cm, find (i) OA (ii) DO.​

Solution:

$\sf (i) Let\;OA\;be\; X\; cm.\\\\\ \sf\triangle\ OAB- \triangle\ OCD\\\\\ \implies\dfrac{OA}{OC}=\dfrac{AB}{CD}\\\\\implies\dfrac{x}{3.5}=\dfrac{8}{5}\\\\\ \implies\ x = \dfrac{8\times 3.5}{5}= 5.6\\\\\ Hence,OA = 5.6cm.$

$\sf (ii)Let\;OD\;be\;Y\;cm.\\\\\implies\triangle\ OAB-\triangle\ OCD\\\\\implies\dfrac{AB}{CD} = \dfrac{OB}{OD}\\\\\implies\dfrac{8}{5}=\dfrac{6.4}{y}\\\\\implies\ y = \dfrac{6.4\times 5}{8}\\\\\ Hence,DO = 4cm.$

Note:

This question is related to a figure.But you haven't post.Please try to Attach figure If question is related to the figure.So,It help us to understand well.

Well,Now I have attached the picture.
