If the whole angle (ABC) is equal to 133, we can add angles ABD and DBC to find x.

10x+13=133
Subtract 13 from both sides to get
10x=120
Divide both sides by 10 to get that x=12

We can now plug the value of x into ABD to find its measure.
7(12)+4
Simplifies to 84+4, which is 88

So angle ABD is equal to 88 degrees.

  x = 6 . . . . . . . . . . . . . multiply by 2

6 liters of pure concentrate must be added to make a 50% punch.
