Answer:
The answer would be D or 8 bc 8x1=8 8x2=16 and that would be the GCF.
Step-by-step explanation:
All of them are, except ' π ' (pi) ... which gives you an idea of why
that one is usually written as a symbol and not as digits.
Here's a useful factoid regarding the other numbers on the list:
-- <em>ANY</em> number that you can write down on paper, <u>completely</u>,
using digits, is a rational number.
The tree is 820 inches tall using the similarity of triangles.
To get the height of the tree, we will use the properties of similar triangles expressed as:

- Note that 1 foot = 12inches
- 7ft = 84in and 82ft = 984in
- h is the required height of the tree. Simplify the equation above to get the height "h" and replace feet with inches;

Hence the tree is 820 inches tall using the similarity of triangles.
