  • Hey guys lets review for our trigonometry test 
  • Now this one is SOH because we are looking for the opposite and the hypotenuse is given to us. The equation would be Sin (43°)= X over 12. Then multiply 12 from X over 12 to get X alone. Now the equation reads 12 multiply sin(43°).
  • Oh brother! Why?
  • Right now?! 
  • Now this one is CAH because we are given the adjacent and looking for the hypotenuse. The equation is cos(27°)= 5 over Y. Since you still have to get the variable by itself the equation would now be Y= 5 over cos(27°) 
  • Let's get started. We are gonna go through SOHCAHTOA. So picture the roof on the house as triangle standing up forming a right triangle.
  • The hypotenuse is across from the 90 degree angle. The opposite is across from the angle that isn't 90°. The adjacent is next to the angle that isn't 90°.
  • In this problem it would be TOA because we are looking for the opposite and the adjacent given along with the angle.
  • X O
  • 10 A
  • So the answer would be 7.81=X?
  • 38°
  • So the equation would be tan (38°)= X over 10. Then you would have to multiply 10 from X over 10 to get X alone. Now the equation would be 10 multiply tan (38°). 
  • Tan like I need to tan in the sun ?
  • Yes, you're getting it.
  • uhhh not quite like that type of  tan.
  • Yes!!! You all are getting it.
  • I'm SOH over this!
  • 43°
  • 12 H
  • X O
  • is the answer 8.18=X?
  • So would the answer be Y=5.61?
  • 5 A
  • 27°
  • Y H
  • yes! You will do great on the test tomorrow.
  • Call the ambulance, I think I'm understanding this 
  • Finna hit them triangles with that SOH-CAH-TOA
