Re: trig and mitre angles
sin (A) =7/L
cos (B-90)=4/L
A+B+155=360
Hi all,
I just have some basic trig behind me, and i would like some understanding on how to do some calculations.
I will insert an image as my basic model.
Being that the included angle is 155 degrees and the 7 inches and 4 inches are constants.
I would like to know how to claculate for:
angle A
angle B
and "L"
in 3 different calculations.
I would really appreciate some help on this and keep in mind, that I only have basic trig
Thanks
MaxJasper,
Thank you, you won't believe how helpful that was.
I have spent many hours (probably around 14) on a different forum trying to get that answer.
Your answer makes sense to me, others were trying to make a molehill into a mountain and they lost me by making the problem bigger than it was.
now, my solving for 2 unknowns with 3 equations is weak ( many many years since I've done it)
would you mind walking me throught the steps to solve for "L"?
thank you
