Answer:
Step-by-step explanation:
1) pentagon; n= 5
Sum of interior angles = 180*(n -2) = 180* (5-2) = 180 * 3 = 540
2) Sum of interior angles of a polygon = 1080
180*(n-2) = 1080
n - 2 = 1080/180
n -2 = 6
n = 6+2
n = 8
Polygon has 8 sides
3) Sum of interior angles of a polygon = 6840
180*(n-2) = 6840
n - 2 =6840/180
n -2 = 38
n = 38 + 2
n = 40
Polygon has 40sides
4)Sum of interior angles of an octagon = 180*(n-2) = 180* (8-2) = 180 - 6 = 1080
The sum of the interior angles of the 10-sided polygon on the left is 1440 °.
The answer is : 1440

Answer:
450
Step-by-step explanation:
For the answer tot he question above, let the number of t-shirts are represented by 't'
number of sweaters are represented by 's'
cost of 1t=10 and cost of 1s=20 so
10t+20s=2000 or (factor out the 10 if you want to simplify)
10(t+2s)=10(200)
divide both sides by 2
t+2s=200
