Answer:5.6
Step-by-step explanation:2.8×12=12×9.8-8/3v^2
33.6=117.6-8/3v^2
8/3v^2=117.6-33.6
8/3v^2=84
8v^2=84×3
8v^2=252
V^2=31.5
V=√31.5
V=5.6125
V~5.6

The solution to this puzzle is 10+3 = 13
<h3>How to solve the puzzle</h3>
To solve this the values at the top of the star were gotten by the addition of two values inside the stars.
- 3 + 12 = 15
- 12 + 4 = 16
- 4 + 2 = 6
- 2 + 10 = 12
- 10 + 3 = 13
Therefore the answer to this question is 13.
Another way of getting the value is by adding 15 + 16 = 31
12 + 6 = 18
31-18 = 13
