319.554 is what the calculator spits out :) that is if 79/6 is a good number. 12 and 50/60 = 12 5/6 = (72+5)/6 = 77/6 gotta recalc it :)

these are basically tan problems

oh ok
amistre64
  • amistre64
[30(60)+5]/60 is going to be the number for my degrees.. tan(n) = 1065/x x = 1065/tan(n)...

1838.453 double check that...

  • amistre64
1838.453 its what I get :)

amistre64
  • amistre64
nope... messed up someplace... my number for degrees specifically..
amistre64
  • amistre64
[30(60)+ 25] /60
amistre64
  • amistre64
recalculating....

  • amistre64
1814.03 is what i get with the right numbers :)
anonymous
  • anonymous
i did it that way and got 1838.7
anonymous
  • anonymous
wow lol
amistre64
  • amistre64
I added a "5" it aint 5/60 minutes... its 25/60 minutes so I had to get the right number for degrees :)
anonymous
  • anonymous
oh ok
amistre64
  • amistre64
im sure its 1814, or close to that :)
