do you have the graph of \(y = 3\tan\theta \)
BloomLocke367
  • BloomLocke367
yes
ganeshie8
  • ganeshie8
good, \[y = 3\tan\theta\] plugin \(\theta = 30, ~60\)
BloomLocke367

\(\Large\sqrt3\) and \(\Large3\sqrt3\)
ganeshie8
  • ganeshie8
looks good, done with part b ?
BloomLocke367
  • BloomLocke367
that's it?
ganeshie8
  • ganeshie8
thats it for part b
BloomLocke367
  • BloomLocke367
okay.

  • BloomLocke367
so for c, I do \(\sqrt3\times6\div2\), then \(3\sqrt3\times6\div2\)?
ganeshie8
  • ganeshie8
Perfect!
BloomLocke367
  • BloomLocke367
so I got \(3\sqrt3\) and \(9\sqrt3\)
ganeshie8

simply divide the total area of patio by the tile area
BloomLocke367

so \(140.4\div3\sqrt3\) and \(140.4\div9\sqrt3\)?
ganeshie8
  • ganeshie8
careful about the units you need to convert both to same units before dividing
BloomLocke367
  • BloomLocke367
ohh how do I do that?
ganeshie8
  • ganeshie8
1 ft = 12 in
BloomLocke367
  • BloomLocke367
oops, I see now. the smaller triangles are in inches XD
BloomLocke367
  • BloomLocke367
so \(1684.8\div3\sqrt3\) and \(1684.8\div9\sqrt3\)?
ganeshie8
  • ganeshie8
looks neat
BloomLocke367
  • BloomLocke367
324.24 and 108.08
