Answer:
If a polygon is convex, then the sum of the measures of the exterior angles, one at each vertex, is 360° .
Consider the sum of the measures of the exterior angles for an n -gon.
N=180n−180(n−2)
Distribute 180 .
N=180n−180n+360 =360.
Step-by-step explanation:
It can be either 1.4 or 1.3 or your looking to your nearest 5th
So we are going to make this into a equation and evaluate it:
20 = (n ÷ 5) x 2
This is a two-step equation.
First we divide both sides by 2. We now have:10 = n ÷ 5
Then we multiply each side by 5. Now we have the final answer:50 = n
The two-digit number is 50, hope this helps!

General Formulas and Concepts:
<u>Algebra I</u>
- Standard Form: ax² + bx + c = 0
- Factoring
- Finding roots
Step-by-step explanation:
<u>Step 1: Define equation</u>
5u² + 6 = -13u
<u>Step 2: Solve for </u><em><u>u</u></em>
- Rewrite: 5u² + 13u + 6 = 0
- Factor: (u + 2)(5u + 3) = 0
- Find roots: u = -2, -3/5
