If POR ~ ASTU, what is the scale factor of APQR to ASTU?<br> A. 1/5<br> B. 1/4<br> C. 5<br> D. 4

MariettaO [177]

Answer:

$k = \frac{1}{5}$

Step-by-step explanation:

Given

The attached triangles

Required

The scale factor

From the attachment, we have:

$TU = 4$

$QR = 20$

So, the scale factor from PQR to STU is:

$k = \frac{TU}{QR}$

$k = \frac{4}{20}$

$k = \frac{1}{5}$
