Storyboard Text

  • Gabby stepped outside her house for a slight second to get the mail. Without realizing, the door locks behind her. She has no way to get in, but through her balcony.
  • "TRIGONBALCONY"
  • Gabby is standing 18 feet away from the balcony at an angle of 57°. She wants to know how high the balcony of her bedroom is. To do so, she uses trig and does 18 times tangent(57). Therefore, she finds out that the balcony is 28 feet high.
  • 57°
  • 18 feet
  • x
  • She suddenly realizes that the balcony of her parents' room is closer, which is 12 feet high, and Gabby's angle to the balcony is 50°. She wants to know how far she is from her house. She uses trig and divides 12 by tangent(50). She is 10 feet away from her house. 
  • 50°
  • x
  • 12 feet
  • She looks to her right and there is a ladder laying on the grass. She wants to know how tall she has to make the ladder to reach the 12 feet balcony at a 52° angle. To figure this out, she divides 12 by sin(52). The ladder has to be 15 feet. 
  • x
  • 52°
  • 12 feet
  • Since she knows she is 10 feet from her house, which is 12 feet tall, she wants to find her angle of elevation. Gabby uses Tan-1(12/10), so her angle of elevation is 50.2°.
  • 10 feet
  • 12 feet
  • Finally, Gabby is able to get into her house through her parents' balcony with the help from the ladder!  THE END!
