I know that but I'm not sure I know x=opposite and 50 is adj
anonymous
  • anonymous
solve for the other angle
anonymous
  • anonymous
you have the corner angle as 54 degrees?
pokemon23
  • pokemon23
in this case is this a tan?
pokemon23
  • pokemon23
Tan(36)*41

  • pokemon23
so? i did it correctly?
anonymous
  • anonymous
So Tangent = Adjacent over Opposite
anonymous
  • anonymous
understand?
pokemon23
  • pokemon23
so x=64.35
pokemon23
  • pokemon23
but its say nearest centimeter
anonymous
  • anonymous
Messed that up sorry. It's going to be tan(54) = x/50
anonymous
  • anonymous
so solve for that.
anonymous
  • anonymous
Tell me: Tan(54) = ?
pokemon23
  • pokemon23
1.37638192
anonymous
  • anonymous
now solve using SOHCAHTOA
anonymous
  • anonymous
so tan(54) = x/50
anonymous
  • anonymous
so 1.376 = x/50 x = ?
pokemon23
  • pokemon23
I got 68.81
anonymous
  • anonymous
correct
anonymous
  • anonymous
round to nearest cm
pokemon23
  • pokemon23
which i 68.80 if im right
anonymous
  • anonymous
whole centimeter bud
anonymous
  • anonymous
so if you have 65.36 centimeters, rounding to 65.4 isn't rounding to the nearest centimeter, that would be millimeter.
pokemon23
  • pokemon23
facepalm..........
anonymous
  • anonymous
you have to round to the nearest centimeter which would be 69
anonymous
  • anonymous
understand?
pokemon23
  • pokemon23
so just 69.
anonymous
  • anonymous
should be
anonymous
  • anonymous
but do you understand why?
pokemon23
  • pokemon23
can you explain to the nearest centimeter.
anonymous
  • anonymous
well if you have 66.74 centimeters that means you have 66 WHOLE centimeters and .74 of a centimeter correct?
anonymous
  • anonymous
so why would you round to 66.7 centimeters? You would still have 66 centimeters and .7 of a centimeter
anonymous
  • anonymous
Instead, you round to the next WHOLE centimeter which is 67, make sense?
pokemon23
  • pokemon23
because of third digit is higher than 5 it raises the number right.
anonymous
  • anonymous
yes 5+ = round up 4- = round down
anonymous
  • anonymous
so round these to the nearest centimeter for me: 55.34 = ? 57.49 = ? 73.50 = ? 110.2 = ?
pokemon23
  • pokemon23
kk
pokemon23
  • pokemon23
55 57 74 110
anonymous
  • anonymous
correct :)

  • pokemon23
I think I got them all wrong T_T
pokemon23
  • pokemon23
oh.
anonymous
  • anonymous
