Answer: 1.2 is the length between QR

Step-by-step explanation: We see that BC is similar to QR. BC is 2. If we look at other angles and compare the two, we see the scale is 1.666666666666667. 1.6 simply put. So if we divide 2 by 1.666666666666667, we get 1.25. Since the other decimals only go to the tenths, we put 1.2.

Answer:

Side QR is 1.2 units long.

Step-by-step explanation:

Quadrilaterals ABCD and PQRS are both similar. The scale factor from ABCD to PQRS is 3/5. Figure this out by dividing corresponding sides.

1.8 / 3

18 / 30

3 / 5

Side BC (the side that corresponds to QR) is 2 units long. Multiply that by 3/5 to get the length of QR.

2/1 * 3/5

6/5

Side QR is 1.2 units long.
