1) Would be c+15 because you can combine 19-4
2) Would be m+2 because you can combine 12-10
Step-by-step explanation:
I'm guessing
second one
removing some of the sentences
The diameters intersect at the center of the circle
m<BKD = 100
<AKC is vertical to <BKD, so m<AKC = 100
An arc has the same measure as its central angle,
so m(arc)AC = 100
Step-by-step explanation:
Mean= The data points that add up, or, the sum of all data points, divided by the number of data points, will give you the answer,
So
20+50+30+40+60+80 would be
100+40+60+80 which is
200.
Since there are 6 numbers in the problem, we do
200/6
which will give us
33.33 etc. (33.3333333333 on and on forever)
