Question

What is the ratio for sine

Answer 1

Blank 1: opposite

Blank 2: adjacent

Blank 3: opposite

Blank 4: adjacent

Explanation:

There is a trigonometric acronym for this which is:

Soh Cah Toa

Soh means that sine is opposite over hypotenuse.

Cah means that cosine is adjacent over hypotenuse.

Toa means that tangent is opposite over adjacent.

Let me actually write these out as fractions:

sine is
`\frac{\text{opposite}}{\text{hypotenuse}}`

cosine is
`\frac{\text{adjacent}}{\text{hypotenuse}}`

tangent is
`\frac{\text{opposite}}{\text{adjacent}}`

Blank 1: opposite

Blank 2: adjacent

Blank 3: opposite

Blank 4: adjacent
