Answer:
C
Step-by-step explanation:
A is for sure wrong because we can see the distribution of the data showing us that the center is at 8. B is also wrong because the spread is only from 6.5 even though the table goes from 5. C would be correct because its symmetrical in shape.
Answer:
a=70 vertically opp angles
b=80 linear pair
c=100 corresponding angles
d= 80 linear pair with c
e= 180 -a-d
=180-70-80
=30
10.5 divided by 8 should be 1.3125
Cosine again. Yay.
Put 36 into a fancy calculator with one of those cos() things. You get about 0.81.
So that's the ratio between x and 10.
So basically x/10 = 0.81, or 0.81 * 10 = x.
8.1 = x
It may be can be number 1 (a)
