It should be just the 6 because it is only the 6 that is repeating.
I believe it is b) x=-5 only
In any polygon with number of sides = n, the sum of measures of its internal angles is equal to (n-2)*180
Now, for a nonagon:
number of sides = 9
sum of internal angles = (9-2)*180 = 1260 degrees
We are given the measures of seven of its angles and we know that the other two are equal. Assume that each angle of the remaining two angles has a measurements = x degrees
Therefore:
sum of angles = 138 + <span>154 + 145 + 132 + 128 + 147 + 130 + x + x
1260 = 974 + 2x
2x = 1260 - 974
2x = 286
x = 143 degrees
Based on the above calculations:
The measure of each angle of the remaining two angles is 143 degrees</span>
I just answered this question(s). mean is average. So you just add all the numbers up per country and divide by how many numbers there are. I hope you know how to graph otherwise look it up on kan academy and the country with the lowest number for height is the gold medalist. And the top three fastest go as gold, silver and bronze<<<<in this specific order.
