Answer:
x = 114
Step-by-step explanation:

∠ C = ∠ D , that is
x + 18 = 132 ( subtract 18 from both sides )
x = 114

Answer:
D 
Step-by-step explanation:
choice A is not guaranteed since the values varied from 0 to 7.

choice C is incorrect because 50% are less than 3.12 and 50% are greater than 3.12.
choice D seems pretty good, since it says average, long run, approach, etc.
choice E is incorrect because it says "will be". It is not definite.
