Answer: D 1800 degrees

Step-by-step explanation:

The sum of the interior angles can calculated by using the formula 180(n-2) where n is the number of sides of the shape. Plug 12 in for n and you'll get 1800 degrees which is the sum of all the interior angles in the polygon. Hope this helps :D

Answer: 10 and -4

Step-by-step explanation:

3x - 2 Plug in 4 for x

3(4) - 2 = 12 - 2 = 10

5x + 6. Plug in -2 for x

5(-2) + 6 = -10 + 6 = -4

If AE=6x-55 and EC=3x-16, find DB. (Hint: Find x first and then substitute.)
erica [24]

<u>Given</u>:

Given that ABCD is a rectangle.

The diagonals of the rectangle are AC and DB.

The length of AE is (6x -55)

The length of EC is (3x - 16)

We need to determine the length of the diagonal DB.

<u>Value of x:</u>

The value of x can be determined by equating AE and EC

Thus, we have;

AE=EC

Substituting the values, we get;

6x-55=3x-16

3x-55=-16

       3x=39

         x=13

Thus, the value of x is 13.

<u>Length of AC:</u>

Length of AE = 6(13)-55=78-55=23

Length of EC = 3(13)-16=39-16=23

Thus, the length of AC can be determined by adding the lengths of AE and EC.

Thus, we have;

AC=AE+EC

AC=23+23

AC=46

Thus, the length of AC is 46.

<u>Length of DB:</u>

Since, the diagonals AC and DB are perpendicular to each other, then their lengths are congruent.

Hence, we have;

AC=DB

 46=DB

Thus, the length of DB is 46.
