The sum of the interior angles of a hexagon is 720 degrees. If 3 angles are congruent, each with measure x degrees, and the other 3 angles are also congruent to each other, each with measure 2x degrees, then the total sum of all 6 angles would be 3x + 3(2x) = 9x. If this is equal to 720, then x = 80 degrees, while 2x = 160 degrees.
Therefore, there are 3 80-degree angles and 3 160-degree angles.
so, 7 is neutral anything past 7 is considered basic.
answer: <em>a water and ammonia solution with a pH of 11 (very basic).</em>
<em />any number under 7 is acidic and of course there are different degrees of acidic just like there are different degrees of basicity.
______________________________________________________________
- stomach's digestive juices, would be considered very acidic
-apple juice is also acidic but not as acidic like stomach juices.
- grape juice, is becoming less acidic.

Hopefully this helped and good luck.
<span>S = 2Πrh + 2Πr2
Manipulating the equation for h.
Step 1. subtract </span><span>2Πr2 on both sides.
</span>S - 2Πr2 = 2Πrh + 2Πr2 - 2Πr2
S - 2Πr2 = <span>2Πrh
</span>
Step 2 . divide <span>2Πr on both sides
</span>
(S - 2Πr2)/2Πr = 2Πrh/<span>2Πr
</span><span>h = </span>(S - 2Πr2)/2Πr
The vertex would be at (5,-2)
