Answer:
6:15 and 8:20 are examples of additional equivalent ratios.
Step-by-step explanation:
The table is:
<u>Books (x) Cost (y)</u>
2 5
4 10
From the table, the ratio Books : Cost is 2:5 or 4:10. Equivalent ratios are obtained, using a graph, from the plot of the line that pass through these two points. In the figure attached, this line is shown. There, it can be seen that ratios 6:15 and 8:20 are equivalent to those from the table.

<span>−<span>45</span></span>
<span><span>
</span></span>
Explanation:
Since <span><span>tan<span>(θ)</span></span>=<span>34</span>>0</span> and <span><span>sin<span>(θ)</span></span><0</span>, θ is in quadrant 3 (since <span><span>tan<span>(θ)</span></span>>0</span> iff θ is in quadrant 1 or 3 and <span><span>sin<span>(θ)</span></span><0</span> iff θ is in quadrant 3 or 4).
<span>cos<span>(θ)</span></span> must then be negative.
