Answer:

12.8 or option 3

Step-by-step explanation:

So this is actually a proportion:

The large triangle to the smaller one:

The angles of the triangles are the same so they are proportional

We know the larger one is 20/8 times the smaller one's sides because

YZ =  something times QR so:

20 = 8 times 20/8

In order to find PR, we have to divide ZX by the proportion rate thing so:

32 / (20/8)

= 32 * 8/20

= 64/5

= 12.8
