Storyboard Text

  • How tall do you think this light pole is?
  • X
  • I’m not sure, but we can use trigonometry to find out.
  • How are we going to do that?
  • First, imagine there’s a triangle here.
  • It looks like there’s a 40° angle of elevation and the distance to the pole is 7 feet.
  • 40°
  • 7 feet
  • X
  • We know this is a right triangle, and now we need find the height.
  • We need to use SOHCAHTOA to figure out the height. We know the adjacent side and the angle.
  • 40°
  • 7 feet
  • X
  • That means we will use tangent and the formula will be tan40=x/7
  • The height of this light pole is 5.9 feet.
  • 40°
  • 7 feet
  • 5.9 feet
  • 40°
  • 7 feet
  • Good job, now you know how tall the pole is.
