You know angles B and C are both 60°, the values of the angles in an equilateral triangle. Since the sum of angles in a quadrilateral is 360°, you have
B + C + x + y = 360°
60° +60° + x + y = 360°
x + y = 240°

Hello there! So, we find the total cost in dollars by multiplying the price of the cleats by the percent of tax. However, we first need to add 1 to the tax rate in decimal form. 6.5% is 0.065 in decimal form. Now add 1 to that number to get 1.065. Let's multiply. 59.99 * 1.065 is 63.88935 or 63.89 when rounded to the nearest hundredth. There. Darin will pay a total of $63.89.
Note: When it comes to finding the total price of something with tax, add 1 to the percentage rate in decimal form, and then multiply that number by the price to get the total amount. This will help you out, make things easier, and save time.
The answer is A or the frist one since there really isnt letters
