Mathematics

ZX = 4cm

Step-by-step explanation:

Given

$\triangle PQR$ similar to $\triangle XYZ$

$PQ = \frac{1}{2}XY$

RP = 2cm

Required

Find ZX

$\triangle PQR$ similar to $\triangle XYZ$ implies that, the following sides are similar

$PQ \to XY$

$QR \to YZ$

$RP \to ZX$

To find ZX, we make use of the following equivalent ratio

PQ : XY = RP : ZX

Where

$PQ = \frac{1}{2}XY$

RP = 2cm

So, we have:

$\frac{1}{2}XY : XY = 2cm : ZX$

Express as fraction

$\frac{\frac{1}{2}XY }{ XY }= \frac{2cm }{ ZX}$

$\frac{1}{2}= \frac{2cm }{ ZX}$

Make ZX the subject

ZX = 2 * 2cm

ZX = 4cm
