Answer:
6
Step-by-step explanation:
6 times 5 is 30. You would've divided 30 by 5
The sum of two adjacent sides is 11 inches, so the long sides are 9 inches. The "unknown number" must be 12.
EF = 50 in.
In similar figures, corresponding sides are proportional. We use the similarity statement ABCD~EFGH to write a proportion:

Cross multiply the proportion:
45*x = 75*30
45x = 2250
Divide both sides by 45:
45x/45 = 2250/45
x = 50
