Answer:
Step-by-step explanation:
Number of side = n = 7
Sum of interior angles of 'n' sided polygon = (n - 2) *180
= (7 - 2)* 180
= 5 * 180
= 900
x + 150 + x -20 + 140 + 120 + x + 20 + 130 = 900
Combine like terms
x +x +x + 150 - 20 + 140 + 120 + 20 +130 = 900
3x + 540 = 900 {Subtract 540 from both sides}
3x = 900 - 540
3x = 360 {Divide both sides by 3}
x = 360/3
x = 120
Interior angle Exterior angle
∠A = 120 180 - 120 = 60
∠B = 130 180 - 130 = 50
∠C = 120 + 20 = 140 180 - 140 = 40
∠D = 120 180 - 120 = 60
∠E = 140 180 - 140 = 40
∠F = 120 - 20 = 100 180 -100 = 80
∠G = 150 180 - 150 = 30
Answer:
At approximately
16 c a cup, Folgers Coffee is better value than Seattle's Best which costs
18 c a cup.
7:2....added = 9
7/9(180) = 1260/9 = 140 fluid oz .....mixed fruit
2/9(180) = 360/9 = 40 fluid oz <== lemonade
To find the mean/average of a set of numbers, add them all together then divide by the number of numbers.
249 + 449 + 269 + 259 + 329 = 1555
1555/5 = 311
The answer is $311
