Oh Help! A Hill Of Ants!
Opposite/Hypotenuse = Sine
Adjacent/Hypotenuse = Cosine
Opposite/Adjacent = Tangent
Sally?
Oscar?
Don't make me say it!
Then the hypotenuse is 104.625 divided by the sine of 73 degrees. the sine of 73 degrees is 0.9563, so the hypotenuse is 109.406.

I had a college roomamte that had trouble remembering that. So he got a large piece of poster board and put it up on a wall. Being helpful “elves,” insert evil grin here, we helped him out by writing it on pieces of paper we put everywhere. It was taped to the face of his clock. It was on pieces of paper in the pockets of his coat. It was written on the toilet paper. It was on a small piece of paper inside his stapler. It was inside his shoes. Inside his books.
He was not amused.
When I went through Advanced First Term Avionics (AFTA) way back in 1982, scientific calculators had only been in use for about 3 years. On a work crew in the AFTA building we threw out about 400 slide rules. The petty officer in charge of the work crew said that the first 2 weeks of the program used to be to each you how to use a slide rule and they were able to shorten the program by that much when they went to calculators.
Simple Trig Functions above. If you know the angle and one side length then you are fat.
Sine = Opposite / Hypotenuse
Cosine = Adjacent / Hypotenuse
Tangent = Opposite / Adjacent
You can do quite a lot with this and a little imagination.
109.406 is correct. (given side opposite 73 deg angle)
As a member of the secret society of the technically literate, I’d like to remind you all of the secret rule: Never answer a simple question privately. If the person asking is public about asking, then by all means help them and teach them. If the are asking privately so they can pose as a technically literate person, then out them — publicly humiliate them. Answer their question in an e-mail and blind copy their manager. etc. It’s us against them.
In this case, it is not certain how this secret knowledge is to be used by jsh3180.
I hope you’re not calling SuzyQue fat! :o)
Are you logged in?
You math people are sick. I didn’t figure out fractions until Ingrid helped me while in calculus. Thank God for Ingrid. You know who’s worse? ...all the chemistry people who practice the black arts of transmogrification. Merlin would be proud.
I’m so glad I’m not a ‘real’ engineer...
See post 12. You have one side, two angles. Find other side using tangent of angle. Hypotenuse is then found by Pythagorean Theorem.

If that were true, books of trig tables wouldn’t have cost $50 when I was in High School! :o)

Just what kind of engineer are you?
Cheers!

Thems musta bin Dog years!
I got my first shirt pocket scientific in 1970. Prior to that I used a Compucorp “cigar box” scientific for about three years.
Hey, hey there. Y’all be careful with that kind of talk!
I know that the Scientologists offer free IQ tests. Perhaps they could help you with trigonometry as well.
Can I come out from under the table now?
