Answer:
z = 15
Step-by-step explanation:
The sum S of the interior angles of a regular polygon is given by the formula
S = (n-2) x 180 where n is the number sides
Here n = 9
So S = (9-2) x 180 = 7 x 180 = 1,260
There are 9 interior angles and each angle is (5z + 65)
So the sum of all 9 interior angles = 9 (5z + 65)
= 45z + 585
Set these equal to each other and solve for z
45z + 585 = 1260
45z = 675
z = 675/45 = 15

ahaha but for real it is 19
Answer:
x = 4
Step-by-step explanation:
Cross multiply:
21*2 = 14(x - 1)
42 = 14x - 14
14x = 56
x = 4
Answer:
Step-by-step explanation:
<u>Given equation:</u>
The left side is absolute value, we know it is zero or positive value but never negative.
The right side is negative so the equation can't have solutions as we have contradiction above.
