Re: trig and mitre angles

sin (A) =7/L

cos (B-90)=4/L

A+B+155=360

Re: trig and mitre angles

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

Re: trig and mitre angles

Solve to obtain L = 8.9312"

Re: trig and mitre angles

How did you get the answer?

I don't want the answer, I want to learn how.

Thanks.

Re: trig and mitre angles

can some one give me the equation to solve for L and I will try and figure it out

thanks
