Question

What is tan A?



A.4/5

B.3/5

C.4/3

D.3/4

Answer 1

SOH, CAH, TOA is the way I remember these. Sin is opposite over hypotenuse (OH), cosine is adjacent over hypotenuse (AH), and tangent is opposite over adjacent (OA).
So if you're looking at angle A, you know the hypotenuse is 10, the side opposite from A is 8, and therefore the side adjacent to A is 6. Using the rules I stated above, can you figure out what your fraction should be?

Answer 2

Answer 3

Oh and for the record, I don't just remember the letters in order, I say something more like "so kah toa" and then work from there :)
