Answer: D) The value of 
is between 14.5 and 15
Step-by-step explanation:
Let's start by taking the squaring these numbers.
215 is in between 14.5 squared and 15 squared. That means its square root will be between 14.5 and 15.5
Adjacent and supplementary- the 2 angles are next to each other and they form 180 degrees
When a fraction corresponds to a repeating decimal, it's denominator is 9 or 99.
For example, 4/11 = 36/99 = 0.36 with bar notation over 36.
Example #2: 2/3 = 6/9 = 0.666....
or also written as 0.6 with bar notation over 6.
You know a fraction responds to a terminating decimal because it can be simplified to a terminating decimal.
Example: 2/4 = 0.5
I think it's because if you can't caculate it or you want a rough answer you can estimate. For example you are estimating the height of a tall building. You would just want to estimate it first.
