-3(2/5x-2)=18
multiply -3 by 2/5 and my -2
-6/5x + 6 = 18
subtract 6 from each side
-6/5x = 12
divide by -6/5, multiply 12 by -5/6
x = -10
A polygon is any figure sided with three sides and above such that triangle (3) is the smallest polygon. A nonagon is a polygon with 9 sides. To get the sum of interior angles of a polygon we use the formula;
(n-2) 180 or (n-4)90 where n is the number of sides.
Therefore, for a nonagon the sum of interior angles = (9-2) 180 = 1260 degrees
If we add all the angles we should get 1260, considering the remaining angles to be each x
Thus 138+154 +145 +132 +128 +147 +130 + x +x =1260
= 974 + 2x = 1260
= 2x = 286
= 143
therefore, each of the other angles was 143
Answer: the square root of 3 is: (a number) times ITSELF is equal to 3. Therefore, if you multiply that number times that number again, it is equal to 3.
Ex1- sqrt of 4 times the sqrt of 4 —> 2 times 2 which is 4
Ex2- sqrt of 9 times the sqrt of 9 —> 3 times 3 which is 9
Your Answer is 2/7. I hope this helped
