The property used to arrive at line 2 is the additive property of equalities

The additive property of equalities states that for real numbers if x = y : then x + z = y + z  

For example if 2 = 2 , then 2 + 1 = 3

In order to arrive at line 2, x and 2x were added together to arrive at 3x

The distributive property was used to arrive at line. The property states that : x(1 + 2) = x + 2x

Subtractive property of equalities was used to arrive at line 3

Sphinxa [80]

Answer:

Blank 1: opposite

Blank 2: adjacent

Blank 3: opposite

Blank 4: adjacent

Step-by-step 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
