To solve this problem, we simply need to identify the variables, where sunflowers are "s" and other flowers can be "f". Since we know that there are 8 rows of "f" for every 2 rows of "s", we can find that s=4f. This can lead to the equation:
2s+8f=240; or, when substituted, 2(4f)+8f=240.
We can solve this equation as 16f=240, or f=15.
Now, we can put f into s=4f, and find that s=60. So we can subtract the total number of rows by 60 to find the total number of "f" rows.
240-60=180.
This means that there are 180 rows that are NOT sunflowers.
Hope this helps!

Answer:
Part 1:
Angle DCB is a right angle.
So, angle DCA + angle ACB = 90
Angle ACB = 90 - angle DCA = 90-50=40
Answer is option C. 40
===========================
Part 2:
Angle DCB is a right angle.
So, angle DCA + angle ACB = 90
Angle ACB = 90 - angle DCA = 90-60=30
Answer is option B. 30
