Title: Cant get brain working.....
Post by: hairyasswelder on May 12, 2009, 18:24:13: Have a bit of a puzzle for the mathematical minded person

I need the lengths of b to c and a to c and just cant get my head in gear....... :oops: :oops:

I have used more than 1 method and confused myself...... :doh: :doh:

The numbers in the corners are degrees 8-[

Also no longer got a Zeus book :-.

Post by: Mikieb1981 on May 12, 2009, 18:43:56: Calculate AC

Sin C = Opp/Hyp
Sin 42 = 3050/AC
AC = 3050/Sin 42
AC = 4558.15

Calculate BC

Tan A = Opp/Adj
Tan 48 = BC/3050
BC = Tan 48*3050
BC = 3387.37

Hope that helps

Oh and for future reference

However, I bow to the mathematical genius who can still use Sine, cosine & Tan rules... I used to be able to... but it's been a while...

Dont make a outdoor staircase for a first floor flat ....... 3050 is the height of the door bottom and 42 degrees is the max steepness of the staircase by building regs ;) and keeps the length BC to a minimum.

Rob - go and see the doctor. There must be something wrong. :D :D :D
