Текст на Статията

  • Hi I'm Anya! Today I will be travelling to 3 different countries and measuring famous architecture using Trig!
  • Find height of Big Ben clock tower in London!
  • So: tan60° = x/56 56(tan 60°) = x 96m = xBig Ben is 96m tall!
  • The tower makes a 60 degree angle with the ground.
  • We can use the tangent to find the height.
  • 60°
  • 56m
  • x
  • Let's find the height of the golden gate bridge!
  • So: cos40°=x/8888(cos40°)=x67m = x
  • We can use cosine to find the height (adj over hyp)
  • x m
  • 40°
  • 88m
  • Let's find the angle the Eiffel Tower makes with the ground!
  • We can use the inverse tangent to find the angle.
  • 300m
  • 75m
  • So:tan-1(300/75) = x°75° = x°
  • Wow I went to London, San Francisco, AND Paris! It was so cool finding the height and angles of these structures using trigonometry. I'm so happy I learned this in Math class!
  • THE END
