Answer: Median
You can't use the mode in here, since there are no repeated numbers. But You can use mean and median. If you use the mean, you will get 57. If you use the median, you will get 75.5. This means that the median will give you the best grade.
Explanation:
Mode: The most repeated number.
Median: The Middle number of statistics.
Mean: The average of all numbers.
Sum of interior angle of a triangle is 180 degrees.
2x + 4x + 9x = 180
15x = 180
x = 180/15 = 12
2x = 2 x 12 = 24
4x = 4 x 12 = 48
9x = 9 x 12 = 108
the measures of the angles are : 24 degrees, 48 degrees ,108 degrees
