Answer:
- The sum of the interior angles of the 15-gon
- Each interior angle of the regular polygon
Step-by-step explanation:
As we know that
In any convex polygon, if we may start at one vertex and draw the diagonals to all the other vertices, we would form triangles,
The number of triangles thus formed would always 2 LESS than the number of sides.
As
- The sum of measure of the angles of any triangle is 180°.
Thus,
The sum of the interior angles of the 15-gon will be:
Also
15-gon is regular, it means this total is shared in equal proportion among the 15 interior angles.
And
Each interior angle of the regular polygon will be:
Therefore, we conclude that:
- The sum of the interior angles of the 15-gon
- Each interior angle of the regular polygon
Keywords: regular polygon, 15-gon, triangle

For this case what you can do is the following rule of three:
m ---> 100%
x ----> 115%
Clearing the value of x we have:
x = (115/100) * (m)
x = 1.15 * (m)
Answer:
a simplified expression to represent the number of members this year is:
x = 1.15 * (m)
16x-7≤-71
Add 7 to both sides
16x≤-64
Divide both sides by 16
x≤ -4
Hope this helps! :)
Answer:
15
Step-by-step explanation:
2/3 of 30 is 20, so 1/2 of 30 is 15
24 because she already completed four and if she completes twelve more that that will be 24 hope that helps
