  • And with these 3 methods, you can find the length of any side on a triangle
  • This seems so fun, I wonder where I can apply this to find out the lengths within real life.
  • "The Trio Use Trig In Real Like"
  • 56o
  • I must use trig to figure this out. It's tan(56)*13 and it equals 19.3. The pole is 19.3 feet
  • 13 ft
  • X
  • TAN(56)*13= 19.3
  • 15 FT
  • 25 FT
  • ?
  • 6 FT
  • I have the length of the opposite and hypotenuse legs. I must use Sin-1(15/25) and it equals 36.9 degrees
  • 10 FT
  • After their Math teacher, Mr. Guzman taught them about Sin, Cos, and Tan, Erick, Jessie and James decide to use their new found skills on trigonometry to figure out the lengths within triangles they see every day.
  • While waiting for his friends, Erick noticed a sleeping bird on top of the light post. Erick wanted to know how long was the post. He knew he was 13 ft away from the post and was looking at the bird from the bench at a 560 angle
  • a2+b2+C2
  • Sin Cos Tan
  • SOH CAH TOA
  • C2
  • A2
  • B2
  • While looking around in his basement, James was looking from the bottom of his staircase trying to figure out at what angle to look from to look at the top of his stairs. He knows that his stairs are 15 feet tall and 25 feet long. He uses Sin-1 to figure out the angle.
  • 63o
  • ON their way back to class, Jessie, Erick, and James decide to solve one more problem while heading to class. They decide to find out how long the lockers are in the hallway. They know the lockers are 10 ft high and want to see how long it is while looking it at from a 63-degree angle. They figure out that they have to use Cos (CAH).
  • ?
  • 10/COS(63)=22
  • We have to use Cos to figure it out. It's 10/COS(63) which equals to 22 feet
  • After spending time-solving problems using trigonometry , the students tell their math teacher about how they used the skills they learned in real life. Mr.Guzman was happy to hear and continued on with his Trig lessons.
  • The End
