Answers:
- Sum of the interior angles = 4320
- One interior angle = 166.15
=======================================================
Work Shown:
n = number of sides = 26
S = sum of the interior angles of a polygon with n sides
S = 180(n-2)
S = 180(26-2)
S = 180(24)
S = 4320 degrees is the sum of the interior angles.
i = measure of one interior angle of a regular polygon
i = S/n
i = 4320/26
i = 166.1538 approximately
i = 166.15 degrees is the approximate measure of each interior angle.
Side note: The formula to determine the interior angle i only works for regular polygons. This is because each angle is the same measure.
Answer:
The penguin will walk 75.15 feet in 45 sec
Step-by-step explanation:
<h3>0.5 inches of hair is grown each month</h3>
<em><u>Solution:</u></em>
Given that,
Bethany cut off 18 inches of her hair
It took her 3 years to grow it back
<em><u>How much did her hair grow each month?</u></em>
From given,
length of hair = 18 inches
Number of years = 3 years
<em><u>Convert to months</u></em>
1 years = 12 months
3 years = 3 x 12 = 36 months
<em><u>Thus, length of hair grown in 1 month is given as:</u></em>
Thus, 0.5 inches of hair is grown each month
Since the number 5 is in the tenths place, there are 5 tenths.
If you make a dot at (1,5) which is 1 on the x axis and 5 on the y axis, you will see that the dot is up in the white area, so it is not a solution.
a solution would be in the red area.
