Answer:
<BCD=105 Degrees
Step-by-step explanation:
To solve this problem, you need to use linear pairs
Linear pairs are two angles on the same line divided by a single line between them. Linear pairs will always add up to 180 as they are supplementary.
Therefore, 180-75 will give you x, which is 105
Step-by-step explanation:
Assuming the readable scores are:
100, 82, 95, __ , 90, 81, 75, 83, __
We know the mean (or average) is 85, so:
85 = (100 + 82 + 95 + x + 90 + 81 + 75 + 83 + y) / 9
765 = 606 + x + y
159 = x + y
We know the lowest score is 75, so x and y must be at least 76. Possible answers are:
76 and 83
77 and 82
78 and 81
79 and 80
80 and 79
81 and 78
82 and 77
83 and 76
