I did that and I got an answer of .315 dB I need the answer to be in dB to submit. Can you tell me what I am doing wrong here?

Ya computed the vertical line and was able to see the big triangle I was missing. Thank you for all the help.

I have the same problem. Except instead of 114 dB it's 121 dB. I do not understand where the 1e-12 came from. Can someone tell me please? Also, here is what I have done so far: 121=10log(I/Io) 121/10=log(I/Io) 10^12.1=I/Io Now I do not know what to do... I am stuck there since I...

Now I'm not too sure if I understand you correctly here, but what I make out of your response is that the angle between, I believe it to be 30 degrees; you take the sin of the angle and then multiply that by the force, in this case T. Doing that I arrive at the conclusion that 30Tsin(30) = 72...
