Answer:
B) 12 m
Step-by-step explanation:
Let's set up a ratio:
[tex]\frac{AB}{ED}=\frac{BC}{DC}[/tex]
Plug in the given lengths into the ratio:
[tex]\frac{AB}{2.4}=\frac{35}{7}[/tex]
We can simplify the second fraction:
[tex]\frac{AB}{2.4}=5[/tex]
Multiply both sides by 2.4 (multiplication property of equality):
[tex]AB=5*2.4=12[/tex]
B) 12 m
