Upper triangle: 12x +7x + angle of vertex = 180°
Lower triangle: 7x+6x+1 + angle vertex  =180°
Notice than the angles at the vertex are equal

Then: 12x+7x+angle of vertex =7x+6x+1+angle of vertex
19x =13x+1
6x=1 & x=1/6

6x+1 = 12x because the Z angles are the same

Solve this and you get:

1 = 12x - 6x => x = 1/6

What is the check digit, d, for the UPC bar code number shown below? 0-24679-36163-d
Juli2301 [7.4K]

Answer:

The check digit is 7.

Step-by-step explanation:

Check digit can be calculated by the following way:

  • Add all the digits except the check digit that is the last digit on the   right side.

             Total = 0 + 2 + 4 + 6 + 7 + 9 + 3 + 6 + 1 + 6 + 3

             Total = 47

  •      Add the digits at odd starting from left, double this amount and          finally add it with the total from step 1.

             = 0 + 4 + 7 + 3 + 1 + 3

       Sum =  18

      Doubling the sum = 36

     Adding it with the total from step 1, we get

        Total = 36 + 47

        Total = 83

  •  Subtract the last digit of the total from step 2 with 10, and this will be check digit.

        Check Digit  = 10 - 3

        Check Digit  = 7
