Answer:
F = 105
Step-by-step explanation:
The sum of the interior angles of a polygon with n sides is (n – 2)180.
This polygon has 6 sides so the sum of the interior angles is (6-2) * 180 =
720
Add up the angles
x-60 +x-40 +130 +120 +110 + x-20 +x-20 = 720
Combine like terms
4x +220 = 720
Subtract 220 from each side
4x+220-220 = 720-220
x = 500
Divide each side by 4
4x/4=500/4
x = 125
We want to find angle F
F = x-20
= 125-20
105
Given:
Sprayer and generator
1st Job: 6 hours each for a total of $90
2nd Job: 4 hours sprayer and 8 hours generator for a total of $100
Let x = spayer ; y = generator
6x + 6y = 90
4x + 8y = 100
6x = 90 - 6y
x = 90/6 - 6y/6
x = 15 - y
4x + 8y = 100
4(15-y) + 8y = 100
60 - 4y + 8y = 100
4y = 100 - 60
4y = 40
y = 40/4
y = 10
x = 15 - y
x = 15 - 10
x = 5
Sprayer = 5 per hour ; generator = 10 per hour
To check:
6x + 6y = 90
6(5) + 6(10) = 90
30 + 60 = 90
90 = 90
<span>4x + 8y = 100
</span>4(5) + 8(10) = 100
20 + 80 = 100
100 = 100
A' : -1, 3
B': 1, 2
C': 1, 5
If the number on top is bigger than the number on the bottom then it is more than one. if the number on the top is smaller then the number on the bottom then it is less than one. if the bottom and top number are the same then it is 1.
