Determine XY
To solve for XY, we make use of the tan function, which states that:

In this case:

Substitute 4 for YZ

Make XY the subject


So, the expression becomes:

Rationalize:


(-infinity, 2]. Use the infinity symbol and not the word
Answer:
b < -1
Step-by-step explanation:
Step 1: Write inequality
-3(6b - 1) > 18 - 3b
Step 2: Solve for <em>b</em>
<u>Distribute -3:</u> -18b + 3 > 18 - 3b
<u>Add 18b to both sides:</u> 3 > 18 + 15b
<u>Subtract 18 on both sides:</u> -15 > 15b
<u>Divide both sides by 15:</u> -1 > b
<u>Rewrite:</u> b < -1
