Answer 2

12.9 centimeters

Explanation:

The given equation is

`sin(40\°)=(b)/(20)`

Where
`b` represents the length of the segment AC, according to the given graph.

To find
`b` we just need to isolate it in the given equation,

`b=20sin(40\°)`

Then, we know that
`sin(40\°) \approx 0.64`, so

`b=20(0.64)=12.9cm`

Therefore, the length of segment AC is 12.9 centimeters, rounded to the nearest tenth.
