Answer :

Answer:

18 people in total answered the survey

Step-by-step explanation:

Since the angle of a full circle is 360°, We put it in the denominator of the  fraction as: [tex]\frac{140}{360}[/tex]

Then set [tex]\frac{140}{360}[/tex] = [tex]\frac{7}{x}[/tex] where x is the total amount of people that took the survey.

Cross-multiply the numbers: 140x = 2569

Lastly, divide both sides of the equation by 140 to get x by itself.

x = 18

Therefore, a total of 18 people answered the survey.
