  • Nicholas Beard
  • We have to make sure the chairs and not really close to the table. They are 4.8 feet tall and a 47 degree angle of elevation. Tan(47)=4.8/x. x•Tan(47)=4.8. x=4.8/Tan(47).x= 4.5 feet.
  • Mack is 6'4. He is trying to see how high the billboard is off of the ground. He is standing 4 Ft. from the end of the sign. He is 6'1 off the ground with the level of his eyes. So Tan(58)= A/4 • 4. 4Tan(58). A=6.4 Ft.
  • Burger Joint
  • 58
  • 4 Ft.
  • A Ft?
  • Tanx=5/10. Tan^-1(5/10)=26.6 degrees.
  • He is finding what the angle of elevation is from the bottom of the counter to the top. If the counter is 10 Ft. long and 5 Ft. Tall. 
  • 10 Ft
  • 5 Ft
  • 4.8 Ft
  • x Ft
  • 47 degrees
  • He has to find the distance of the door between this glass panels. The height of the door is 8 feet and the angle of elevation is 67 degrees. Tan(67)=8/x. x•Tan(67)=8. x=8/Tan(67). x=3.4 feet.
  • 8 ft
  • X ft
  • Well both buildings passed the test. Thank you for coming with me.
