The angle in a regular polygon is ((n-2)*180)/n with n being the number of sides. The exterior angles would be (360)/n since exterior angles add up to 360. Therefore, (360)/n= (((n-2)*180)/n)*1/3. Multiplying both sides by n, we get 360=((n-2)*180)*1/3. After that, we divide both sides by 180 and multiply both sides by 3 to get 6=n-2. Therefore, n=8 and it is an octagon

Tv=10x-26 and vx =5x+9 what is the value of x
Lyrx [107]

Since this is an equilateral triangle, TV=VX. You can set TV equal to VX to solve for the value of x. The expression would be 10x-26=5x+9. Subtract 5x from both sides to get 5x-26=9. Add 26 to both sides to get 5x=35. Lastly, divide by 5 to get x=7.

So, your answer would be 7 degrees. Hope this helps!
