<span>Sum of Interior Angles = (Number of Sides -2) • 180 degrees
2,160 = (sides -2) * 180
2,160 / 180 = sides -2
12 = sides -2
sides = 14

(x+2)^2=(x+2)(x+2)
remember
25/5=5 aka
(5^2)/5=5
so
(x^2)/x=x
((x+2)^2)/(x+2)=x+2
Step-by-step explanation:
If two lines, segments, or rays intersect at right angles, then they are perpendicular. If two angles are complementary, then their measures add up to 90 degrees. If two angles' measures add up to 90 degrees, then they are complementary. If two angles are supplementary, then their measures add up to 180 degrees.
If you use the elimination method, add both equations together to eliminate a variable. You will get 5x=15. x=3. Replace x in the equations with 3 to get y =7, so your answer is A, (3,7.) I hope his helped!. Please give brainliest!
