From the markings and lines, we can tell this is an equilateral triangle. Since it is an equilateral triangle, we know that each angle is 60°.
Using this information, we can make and solve an equation:
8y - 4 = 60° <em>(we know that it is equal to 60°, since it is an equilateral triangle)</em>8y = 64° <em>(we added both sides by 4 to get the y's alone on one side)</em>y = 8° <em>(we divide both sides by 8 to find out what just y is)</em>-------------------------------------------------------------------------------------------------------------Answer:
So y is equal to 8°

Answer:
Step-by-step explanation:
The 20% discount amounted to ...
0.20 × $42.00 = $8.40
so the price before tax was ...
$42.00 -8.40 = $33.60
The tax amount is 3% of this value, so is ...
0.03 × $33.60 = $1.008 ≈ $1.01
So the total price paid for the shirt was ...
$33.60 +1.01 = $34.61
Randy paid $34.61 for the shirt after discount and tax.
___
<em>Alternate solution</em>
You can realize that the 20% discount means that Randy will pay 80% of the original price of the shirt. Similarly, the 3% added tax means Randy will finally pay 103% of the discounted price. Then the total price Randy pays is ...
$42.00×0.80×1.03 = $34.608 ≈ $34.61
