The measure of ∠FDE = 18°
<u>Explanation:</u>
A Pentagon has 5 sides and is made of 3 triangles
So, sum of the interior angles of the triangle = 180°
Therefore, the total interior angle of a regular pentagon = 3 X 180° = 540°
A regular pentagon will have all its angle equal
All the five angles would make 540°
Let the measure of one angle = x
So,
5x = 540°
x = 108°
Therefore, the measure of each angle of a pentagon is 108°
From the diagram,
∠AED + ∠FED = 180°
∠AED = 108° as it is one of the sides of the pentagon
So,
108° + ∠FED = 180°
∠FED = 72°
In ΔEFD,
∠FED + ∠EFD + ∠FDE = 180°
72° + 90° + ∠FDE = 180°
∠FDE = 18°
Therefore, the measure of ∠FDE = 18°

try mathw4y it helps alot.
I’m not sure if the answer is correct but what I did was 9 times 1 is 9 so what then I did was 9 divided by 88=9.79
As described in statistics the mean standard deviation of the headway is 0.890
what is the statistics ?
The study of statistics is the field that deals with the gathering, structuring, analyzing, interpreting, and presenting of data. In order to apply statistics to a problem in science, business, or society, it is customary to start with a statistical population or a statistical model that will be investigated.
solution:
P(0.995 ≤ x ≤ 1.445) = F(1.445) - F is the given mean value (0.995).
The distribution's cdf is
f(x) = { (1 - 1/x⁶ , x > 1) (0. x ≤ 1)
F(1.445) = 1 - (1/(1.445)⁶)
F(0.995) = 0
Now, using the values of F(1.445) and F(0.995) in P( 0.995 ≤ x ≤ 1.445) to get F(1.445) - F(0.995):
P( 0.995 ≤ x ≤ 1.445)
=1 - (1/(1.445)⁶) - 0
=0.890
Therefore the mean value of standard deviation is 0.890
