Thread: I need help finding this Chord length

Can someone help me figure out the formula for solving Chord DE (see attachment)?

The two formulas I have been trying up till now (with two different results) are...

.50*sin(15+acos((.5-2*.02)/.5) = .3083

or

.50*sin(15+acos((.5-.02)/.5) = .2594


any help will be appreciated. Also, this angle of 15 may need to be changed up/down a bit depending on the situation I encounter, will that be an issue once we find the correct formula?

tiehen please check the attached file. It may be nothing, but my computer is sending up a red flag when I try to open it.

Dan......I'm not sure what to check it's just a pdf that opens up just fine on my computer. When you say "red flag" what does that exactly mean?

Apparently nothing. It's working fine today. Sorry about the mixup.
