The measure of central tendency that is most affected by the lowest score is; A: The mean.
<h3>How to find the measures of Central Tendency?</h3>
The points table is missing and so I have attached it.
The 3 main measures of central tendency are called mean, median and mode.
Now, from the table attached, if we find the average which is the mean, we will get 56.6.
Now, the mode is the number that occurs the most times. In this case, there is no mode because no number appears more than the other.
For the median, if we arrange in ascending order, we have;
42, 48, 49, 53, 55, 56, 58, 66, 68, 71.
The median = (55 + 56)/2 = 55.5
Now, if we remove the lowest score, the measure that will be most affected will be the mean as the median will only change by 0.5 to 56.

Answer:
Step-by-step explanation:
The angles would be supplementary
45 + 5x + 35 = 180
5x + 80 = 180
5x = 100
x = 20
To find out why they are supplementary, refer to the transversal below
∠3 = ∠7 (corresponding angles)
∠8 = 180 - ∠7 (supplementary angles)
And since ∠7 = ∠3...
∠8 = 180 - ∠3 which is why (in the problem) those two angles are supplementary (adding to 180 degrees)
