PLEASE SEE ATTACHED IMAGE.

For this case we have the following equation:

`sin(40)=(b)/(20)`

From here, we clear the value of b which is the length of the AC segment.

We have then:

`b=20*sin(40)`

Doing the calculations we have:

Rounding for the nearest tenth we have:

Answer:

The length of the segment AC is given by:

b = 12.9
