Answer:
35cm
Step-by-step explanation:
The net of a regular pentagon has 10 sides.
Since each of the faces are equilateral triangles, the side lengths are equal.
Therefore:
Length of each side of the net = 70/10 =7cm
Therefore, the base is a regular pentagon of side length 7cm.
The perimeter of the base of the pyramid = 5 X 7
=35cm
The perimeter of the base of the pyramid is 35cm.
F(-x) = 2/-x/ + 3(-x) = 2/x/ - 3x;
The line is right in the middle of 100 and 110 degrees so the answer should be 105 degrees. This tool is called a protractor. :)

Answer:
b.
i. N= 10n+120
= 10*14+120
= 260
ii. N = 10n+120
<=> 190=10n+120
<=> n=7
