Answer:
Side a = 20.8
Side b = 20.5
Side c = 30
Side d = 2
Side e = 12.6
Step-by-step explanation:
We need to know what X is here is the equation:
3.2a+8+12.6+[tex]\frac{1}{2}a[/tex]+5(a+2)+(6a-3.5)=85.9
After doing the math you get a=4.
Apply this to each side and get the answer.
Side a = 20.8
Side b = 20.5
Side c = 30
Side d = 2
Side e = 12.6
Check
20.8+20.5+30+2+12.6=85.9
