For this case we have the following equation:
sin (40o) = b / 20
Clearing b we have:
20 * sin (40o) = b
Therefore, the length of the AC segment is given by:
b = 12.9
Answer:
the length of AC is:
b = 12.9
32 3t try add it all up maybe it work but that's the answer
Answer: 0.92
1-4: stay the same
5-9: round up!
