So hmm notice the picture below
that's the 30-60-90 rule, notice your triangle, the bottom-left-angle is a right angle, 90°, the angle atop is 30°, so the angle on the bottom-right has to be 60°, thus is a 30-60-90 triangle, and as you can see on the triangle on the left in the picture, those are the ratios for it
so 8 will be x, what is the longer leg or side in yours then? well, is

<u>Complete Question:</u>
<em>Hannah was shopping for a summer dress at a store near her home. On the rack where she found the dress she wanted, she saw two signs. The first one read, “Clearance: 15% off.” The second one read, “$10 off—Instant Savings.” The original price of the dress was $65.00. Hannah lives in Oregon, where there is no sales tax.

<u>First Part:</u>
First, 15% off, then $10 off. So
65 - (0.15)(65) = $55.25
Now $10 off makes it:
55.25 - 10 = $45.25
Hannah will pay $45.25
<u>Second Part:</u>
Now, first we have to apply $10 discount, so:
65 - 10 = $55
Now, we apply 15% discount, thus:
55 - (0.15)(55) = $46.75
Hannah will pay $46.75
Answer:
Step-by-step explanation:
Let the number of weeks be x
<u>Then Kendal's CD's</u>
<u>Raymond's CD's</u>
<u>Time when they have equal CD's</u>
- 39 + x = 15 + 3x
- 3x - x = 39 - 15
- 2x = 14
- x = 7 weeks
