|dw:1376252547785:dw| using the drawing i got 16 idk if its right
ganeshie8
  • ganeshie8
thats right ! 15 ft radius + 1ft overhang = 16
ganeshie8
  • ganeshie8
keep going

  • highschoolmom2010
sorry 1 sec
ganeshie8
  • ganeshie8
ok
highschoolmom2010
  • highschoolmom2010
\[\cos (25)=\frac{ 16 }{ x }\]
highschoolmom2010
  • highschoolmom2010
i have forgotten what to do next
ganeshie8
  • ganeshie8
you wanto find x
ganeshie8
  • ganeshie8
maybe multiply x both sides first
highschoolmom2010
  • highschoolmom2010
\[(x)*\cos25= \frac{ 16 }{ x }*(x)\] \[X \cos 25=16\]
ganeshie8
  • ganeshie8
next ?
highschoolmom2010
  • highschoolmom2010
\[\frac{ X \cos 25 }{ \cos 25 }=\frac{ 16 }{ \cos 25 }\]
ganeshie8
  • ganeshie8
perfect !
highschoolmom2010
  • highschoolmom2010
\[x=14.5\]

  • ganeshie8
try again
ganeshie8
  • ganeshie8
looks uve multiplied cos25, instead of dividing
highschoolmom2010
  • highschoolmom2010
16.1

approx 17.6
ganeshie8
  • ganeshie8
lol, yes 17.65 ft but they want the answer in ft and inch
highschoolmom2010
  • highschoolmom2010
ok so i convert ???
highschoolmom2010
  • highschoolmom2010
the .65 is confusing me
ganeshie8
  • ganeshie8
17.65 ft 17 ft + .65 ft 17 ft + .65 x 12 inch ?
ganeshie8
  • ganeshie8
17.65 ft 17 ft + .65 ft 17 ft + .65 x 12 inch 17 ft + 7.8 inch 17 ft 7.8 inches ~ 17 ft 8 inches
highschoolmom2010
  • highschoolmom2010
wow i feel kinda bad for not knowing that :(
ganeshie8
  • ganeshie8
its tricky lol
highschoolmom2010
  • highschoolmom2010
oh yea
ganeshie8
  • ganeshie8
instead of doing all this conversion thingy, we could have simply converted 16 ft to 16x12 inches in the starting itself, and taken the ratio !

when free, you can try this.... skip for now :)
highschoolmom2010
  • highschoolmom2010
ok thanks :D
ganeshie8
  • ganeshie8
actually both are equal. we have to convert anyways in the end, so forget it !
highschoolmom2010
  • highschoolmom2010
oh ok
