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.
