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
