Answer:

1:

we have a rule that is (n-2)×180

while n = number of sides

2:

exterior angle of a polygon = 360 ÷ number of sides

so 360÷25=14.4

3:

octagon is 8 side, so as we said: (8-2)×180 = 1080

4:

lets make an equation, we know that (n-2)×180 = the sum

so (x-2)×180=720

180x -360 = 720

180x = 1080

x=6

RUDIKE [14]
In the given question, there are numerous information's already provided. It is important to note then down first. With the help of those given information's the required answer can be easily reached.
Percentage of students that weighed 140 pounds = 75 percent
Then
Percentage of students that weighed more than 140 pounds = (100 - 75) percent
                                                                                                  = 25 percent
Total number of students that were weighed = 40 students
Total number of students that weighed more than 140 pounds = (25/100) * 40
                                                                                                    = (40/4) students
                                                                                                    = 10 students
So the number of students that weighed more than 140 pounds is 10. So the correct option in regards to the given question is option "1".
