Finding Angles Using Sin, Cos and Tan

What is the correct ratio?

• sin 40 = w/28
• cos 40 = w/28
• tan 40 = w/28
• sin 40 = 28/w

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

• sine
• cosine
• tangent
• cotangent

If you are given the opposite side and hypotenuse, which trig function should you use?

• Adj/Hyp
• Opp/Adj

Cosine ratio represent

• O/H
• A/H
• O/A
