The sum of angles in degree = 180(n - 2), where n is the number of sides of the regular polygon. The sum of angles in degree = 180(n - 2); n = 8 The sum of angles in degree = 180(8 - 2) = 180(6) = 1,080 Angle in degree = (The sum of angles in degree)/n Angle in degree = (1,080)/8 = 135 Thus, in a regular octagon, the degree of an angle is 135.
N - 8
n + (8 + 6)
mn = 8 ( Product) m + n = 6 (Sum) Hence m = 6 - n Substitute (6 -n)n = 8 Multiply out the brackets 6n - n^(2) = 8 n^(2) - 6n + 8 = 0 It is now in quadratic form and will factor Hence ((n - 2)(n - 4) = 0 n = 2 & n = 4 So '2' & '4' are the two numbers. Verification 2 + 4 = 6 2 x 4 = 8
8
Watch closely:The sum of 'n' and '8' is written as (n + 8).
s= -8 + n, or s=n - 8, where s is the sum and n is the number
The sum of the interior angles of an n sided figure is (n-2)*180 degrees So for an 8 sided figure, the sum is 6*180 = 1080 degrees.
It is n + 6.
The sum of 8 and 6 is 14 (8+6)
The sum of -8 and 6 is -2
The expression "eight decreased by three times the sum of a number and six" can be represented as 8 - 3(x + 6). To simplify, first distribute the -3 to both terms inside the parentheses to get 8 - 3x - 18. Combining like terms gives us -3x - 10 as the final simplified expression.
Let's denote the five consecutive numbers as n, n+1, n+2, n+3, and n+4. The sum of these numbers is given by n + (n+1) + (n+2) + (n+3) + (n+4) = 5n + 10 = 40. Solving for n, we get n = 6. Therefore, the five consecutive numbers are 6, 7, 8, 9, and 10.
sum of interior angles = (n-2)180=1080 1080/180=n-2 6=n-2 8=n
