I believe the physical properties are boiling point, freezing point, and water vapor.
Answer:
384√3 in²
Step-by-step explanation:
Given in the question a regular 6 sided polygon
To find it's area you have to use the following formula
<h3> 1/2 x perimeter x apothem</h3>
<em>Perimeter = the sum of the lengths of all the sides </em>
<em>Suppose length of one side = x</em>
<em>Apothem = a segment that joins the polygon's centre to the midpoint of any side that is perpendicular to that side = 8√3</em>
<em />
Since the polygon have 6 sides so
perimeter = 6x
<h3>x = 2(8√3)/√3</h3>
x = 2(8)
x = 16
perimeter = 6(16) = 96 in
plug values in the formula of area
<h3>1/2 x 96 x 8√3</h3>
384√3 in²
Answer:
a = 26°
b = 48°
c = 26°
d = 106°
Step-by-step explanation:
a = c (Alternate angles)
Corresponding angles
(a + d) + b = 180° (Interior angles)
Just solve until the answers are the same
25 times x plus 30 for John
15 times x plus 50 for Mary
10 inches because there are 4 sides of a square so, if the perimeter is 40 inches, to figure out the side lengths you just have to divide the perimeter by 4
