Storyboard Text

  • hey look at that awesome mountain!
  • woah that's cool, its so tall!
  • yea it is, wonder HOW tall...
  • let's use law of cosine to find out!
  • 34
  • X
  • 24
  • I think I've got this one, so first we imagine the mountain as a big triangle...
  • 34
  • you've got it, so it looks like side a and b are 34, and side c is 24
  • 34
  • okay so the formula will be a^2=b^2+c^2 -2 (b) (c) cos A
  • X
  • alright, then to find the angle of elevation with the ground
  • 24
  • 34
  • so to find the angle we would do the square root of 34 times the square root 24 - 2 times 34 times 24 finding angle A
  • X=69.3
  • 34
  • 24
  • 34
  • the angle measurement is 69.3! good job ruby!
  • good job bubbles!
