The straight arrow at the bottom represents 180 degrees.There 3 x's in eqaution so you divide 180 by 3 and you get 60 degrees
Answer:

Step-by-step explanation:
<em>Step 1: Consider the assumption:</em>
Generally,
) is supposed to be the pair of 2 components, in which, the first component is x-component (domain), the second component is y-component (range).
Hence, 
<em>Step 2: Substitute </em>
<em> and </em>
<em> into the inequality</em>

<=> 
<em>Step 3: Simplify</em>
<=> 
<=> 
<em>Step 4: Evaluate</em>
Invalid
Reason: 
<em>Step 5: Conclude</em>
is not a solution to the inequality

First, we want to write an expression for what is given:
(1/5)(1/4)(1/9)(900)
Now, we can solve this. Remember that to multiply fractions, we can just multiply the numerators and the denominators. Also, whole numbers always have a denominator of 1.
(900/180)
