The percentage of green beans and carrots combined is:
11 + 12 = 23%
Then, we can make the following rule of three:
360 degrees -------> 100%
x ---------------------> 23%
Clearing the value of x we have:
x = (23/100) * (360)
x = 82.8 degrees
Answer:
The measure of the central angle for green beans and carrots combined is:
x = 82.8 degrees
