Answer:
[tex]\large \tt {9.2}[/tex]
Step-by-step explanation:
The median of the trapezoid will be calculated using these formula: [tex]\small \tt{m}[/tex] = [tex]\large \tt \frac{1}{2}[/tex][tex]\small \tt{(b_1)+(b_2)}[/tex]
- [tex]\small \tt{m}[/tex] = [tex]\large \tt \frac{1}{2}[/tex][tex]\small \tt{(b_1)+(b_2)}[/tex]
- [tex]\small \tt{m}[/tex] = [tex]\large \tt \frac{1}{2}[/tex][tex]\small \tt{(12.9)+(5.5)}[/tex]
- [tex]\small \tt{m}[/tex] = [tex]\large \tt \frac{1}{2}[/tex][tex]\small \tt{(18.4)}[/tex]
- [tex]\small \tt{m}[/tex]= [tex]\large \tt \frac{18.4}{2}[/tex]
- [tex]\small \tt \blue{m=9.2}[/tex]
