Answer:
The length of the missing side it 8.8.
Step-by-step explanation:
Since we know the equation, we can find the missing side.
=> 113.7 = 38.2 + 2(7.9) + 19.1 + 3(10.6) + x
=> 113.7 = 38.2 + 15.8 + 19.1 + 31.8 + x
=> 113.7 = 104.9 + x
=> x = 8.8
Conclusion:
Therefore, the length of the missing side it 8.8.
