The degree of A would be 85.8 because it has to add up to 180
A² - 225 = (a-15)(a+15)
..................................................................
You add 1/6 to both sides
Step-by-step explanation:
-8 I think because it has a pattern

None of the above.
Step-by-step explanation:Yes, all of the sides match, which would make it an equilateral polygon. However, it is not an equiangular polygon because not all of the angels are the same. In this case, since the angles do not mach and only the sides do, this is not a regular polygon. This is what leads me to believe that is none of them. All of the sides must be congruent and all interior angles must also be congruent.
