7 and 12 Find the measure of angle x. Round your answer to the nearest hundredth. (please type the numerical answer only) (30 Po
goldfiish [28.3K]

Answer:

Angle Y = 35.69 degrees

Step-by-step explanation:

We can use some simple trigonometry to help us out. Here we know that side 7 is the opposite side relative to angle y, and  12 is the hypotenuse.

We think what trig ratio involves comparing opposite and hypotenuse. Sine is opposite over hypotenuse and we can set up a equation to solve.

Sine (Angle Y) = Opposite Side / Hypotenuse

Sine (Angle Y) = 7/12

(Angle Y) = Sine inverse (7/12)

Angle Y = 35.69

A CD usually sells for $17.00. If the CD is 30% off, and sales tax is 8%, what is the total price of the CD, including tax?
Mademuasel [1]

Answer:

First find what the sale price of the CD is. 30% off means the CD is selling for 70% of the original cost ( 100%-30% = 70%)


Multiply the original cost by 70%:

17.00 x 0.70 = $11.90 ( sale price)

Now you need to multiply the sale price by the tax percentage to find the amount of tax:

11.90 x 0.08 = 0.95 ( tax)


Now add the sale price and the tax for the total cost:

11.90 + 0.95 = $12.85
