Question

Find the length of CA

Answer 1

Any similar triangle the ratio of corresponding length is equal.

that mean:

Then:

`(AB)/(XY)=(BC)/(YZ)=(AC)/(XZ)`

Similarly :

`(ED)/(CB)=(EA)/(CA)=(DA)/(BA)`

let CA is x then:

`\begin{gathered} (ED)/(CB)=(EA)/(CA) \\ (10)/(5)=(12)/(x) \\ x=(12*5)/(10) \\ x=6 \end{gathered}`

so value of CA is 6 units.
