Using the sum of interior angles formula;
(n-2)×180=sum
(n-2)×180=2880
n-2=2880/180
n-2=16
n=16+2
n=18
Therefore, this polygon would have 18 sides.
Hope I helped :)
Answer:
4
Step-by-step explanation:
[45-27]÷9·2
18÷9·2
2·2
20 / 4 = 5 miles per hour
5 x 10 = 50 mile in all 10 hours
Fred can hike 50 miles in 10 hours total
To solve this problem, simply use one variable to represent the number of students in each of the 2 classes.
1st class - X = no of students
2nd class - X + 6 no of students
Both classes : X + X + 6 = 50
2X + 6 = 50
2X = 44
X = 22.
1st class - X = 22 students
2nd class - X + 6 = 22 + 6 = 28 students.
There are 28 students in the larger class.
15 = 3*5
64= 2*2*2*2*2*2
There are no common factors so the GCF is 1
