x+23+32+47=180
x+102=180
x=78
O. is the correct answer!!
In isosceles triangles, all angles = 180 degrees and two angles are the same.
Therefore, the two remaining angles equal 69 degrees
180 - 42 = 138
138/2 = 69
Answer:

Median = 82

Maximum = 100
is the first quartile and is the median of the lower half of the data set. 25% of the numbers in the data set lie below
and about 75% lie above
.
is the third quartile and is the median of the upper half of the data set. 75% of the numbers in the data set lie below
and about 25% lie above 
i) .About how many students scored 65 or better?

Since we know that 75% lie above
.
So, Number of students scored 65 or better = 
ii)About how many students scored 88 or better?

Since we know that 25% lie above
So, Number of students scored 88 or better = 
Hence 225 students scored 65 or better and 75 students scored 88 or better.
