Fill in the blank...
SOH ___ TOA

• COH

• CAH

• COA

• CHA

If you are given the two sides that are not the hypotenuse, which trig function should you use?

• sine

• cosine

• tangent

• cotangent

Which Trig function do you use?

• Sine

• Cosine

• Tangent

What about tangent? Use the triangle to answer the following questions. In terms of x and y, what does tanθ equal? tanθ=​ ​ (a)   In terms of sinθ and cosθ, what does tanθ equal? tanθ=​ (b)  

• x

• y

• sinθ

• cosθ

What is the ratio for Sine?

• Hyp/Opp

• Opp/Hyp

• Opp/Adj

• Adj/Opp

Consider SOH - CAH - TOA, what does TOA stand for?

• sin⁡θ=oppositehypotenuse\sin\theta=\frac{opposite}{hypotenuse}

  sinθ=hypotenuse

  
  

  opposite

  ​

• cos⁡θ=adjacenthypotenuse\cos\theta=\frac{adjacent}{hypotenuse}

  cosθ=hypotenuse

  
  

  adjacent

  ​

• tan⁡θ=oppositeadjacent\tan\theta=\frac{opposite}{adjacent}

  tanθ=adjacent

  
  

  opposite

  ​

• tan⁡θ=sin⁡θcos⁡θ\tan\theta=\frac{\sin\theta}{\cos\theta}

  tanθ=cosθ

  
  

  sinθ

What is the correct equation to solve for x ?

• tan( 46 ) = 17/x

• sin ( 46 ) = x/17

• tan (46 ) = x/17

• cos (46) = x/17

What is the correct equation to solve for x ?

• tan (58) = x/11

• tan (58) = 11/x

• cos (58) = x/11

• sin (58) = x/11

What is the correct equation to solve for x?

• tan (45) = x/13

• cos (45) = x/13

• sin (45) = 13/x

• sin (45) = x/13
