Right angle calculator the triangle with 80° bottom edge is 0.125" right side of the triangle is 0.709
2.5-0.709 =1.791

No engineers in this thread. Nope. Not a one.

Yeah, that’s what I got too! Thanks!!!

Is rectangle.
Top/bottom length is 0.125”
Both side is 2.5”

I tried to find some online calculator... but all I found was right triangle & other that doesn’t work w this math.

See attached PDF. the number is 1.791"

Well, don't keep in suspense, what did you do?

I just did exactly like @strat61caster did. find the right triangle first and subtract it.

I’m a software engineer who was forced to take (and retake for that matter) way too many math courses.

Sadly I can’t be arsed to remember all the formulae.

Of course to be honest I wouldn’t say I was able to remember them all at the time, either.

Well, I just finished cleaning out the eves on our house. That will be my last time doing that! I finally agree with mrs humfrz, I have no business being that high up on a ladder.

Therefore, next time it's needed it will be a son-in-law job.

When you get older, they will all come back to you -

However, ....... however ...... what was my point? -

You said that 4 years ago.

I don't remember any formulas, that's what the internet is for. You just have to see whether the problem is indeed fully constrained. If so, find the appropriate formula(s) and crunch numbers. If not, assert assumptions until it is fully constrained.

I think this is kind of a problem, though.

In school they insist on rote memorization almost all the time and so you're kind of forced into using that tool even if you're not skilled with it (I could never be at least for math, no idea why).

And so by the time you're out in the workforce, your best bet is hopefully analyzing a problem by using pattern recognition, which then hopefully leads you to recall similar-ish problems you've come across earlier, and from there you know what to look up to resolve them. But the whole "researching" to find a formula or whatever can be tough.

Especially since with software engineering the ironic thing about the job is that _while_ on the job, everybody Googles and whatever to research stuff they can't remember, but during interviewing you're expected to use rote memorization again.

Yep. It's a common problem when you consider a lot of our teachers and professors were educated pre-internet. I've never applied for a software position so I can't really say much about why that is, but I would guess that if you know concepts by memory you can write effective code/scripts/etc faster than if you have to stop and look it up.

Idk about anyone else, but my college professors actually let us use notes and textbooks on our tests. The test questions were never something they taught directly, but rather more complex problems that would use pieces of what they taught as well as stuff from prerequisite classes. I really liked that because it reinforced the idea that we were there to learn how to engineer, not how to do math.
