Question

VY=27. VZ = 18, and Ww=8, find WX
Х
W
Z

Answer 1

D. 4

Explanation:

∆VWZ ~ ∆VXY, therefore:

`(VW)/(VX) = (VZ)/(VY)`

VW = 8

VX = 8 + WX

VZ = 18

VY = 27

Plug in the values

`(8)/(8 + WX) = (18)/(27)`

Cross multiply

`8 * 27 = (8 + WX)*18`

`216 = 144 + 18WX`

Subtract 144 from each side

`72 = 18WX`

Divide both sides by 18

`4 = WX`

WX = 4
