Question

Find the length of ZV, given the diagram

Answer 1

ZV = 34

Explanation:

Δ XZV and Δ XYW are similar, then ratios of corresponding sides are equal, that is

`(ZV)/(YW)` =
`(XV)/(XW)` , substitute values

`(ZV)/(24)` =
`(17)/(12)` ( cross- multiply )

12 ZV = 408 ( divide both sides by 12 )

ZV = 34

Answer 2

ZV:34

Explanation:

12/24 = 17/X

X = 34

this is called proportional triangles
