Step-by-step explanation:
For a regular 17-gon, the measure of the internal angles is:
a = 158.8°
<h3>
How to measure the internal angles?</h3>
The measure of the sum of the internal angles of a regular figure of N sides is:
(N - 2)*180°
For the case where N = 17, we have:
(17 - 2)*180° = 2,700°
That is the measure of the sum of the internal angles, and we have 17 of them, so the measure of each angle is:
2,700°/17 = 158.8°

This mathematician is named Pythagoras. He was the mathematician who discovered in what relation are the sides, angles, and length of the sides of a triangle. Today this idea is still being used in mathematics and represents one of the foundations in geometry that we use all around.
Answer:
k = 5
Step-by-step explanation:
Given that (x + 1) is a factor of f(x) then f(- 1) = 0
f(- 1) = 3(- 1)³ + 2(- 1) + k
= 3(- 1) - 2 + k
= - 3 - 2 + k
= - 5 + k
Then - 5 + k = 0 ( add 5 to both sides )
k = 5
