Answer: option a.
Step-by-step explanation:
By definition, we know that:
Substitute into the first equation, solve for the cosine and simplify. Then, you obtain:
As then
:
Now we can find :
Mr. Osmond bought a computer that cost $2,500. How much did he pay for the computer if the sales tax rate was 7 present
2 answers:
Answer:
If the sales tax rate was 7%, Mr. Osmond would have bought the $2,500 computer for a total of <u>$2,675</u>.
Step-by-step explanation:
To calculate the total Mr. Osmond paid for his computer, we must find 7% of the computer's cost, $2,500, and then add that figure to $2,500.
To find 7% of $2,500, multiply 2,500 by the decimal form of 7%, .07:
<h2>Since we know that 7% of $2,500 is $175, we can now add that figure to $2,500:
Therefore, we can conclude Mr. Osmond paid a total of $2,675 for the computer.

but anyway, the numerator will give the angles, and θ is just half of each
ok... that's a negative tiny angle, is in the 4th quadrant, if we stick to the range given, from 0 to 360, so we have to use the positive version of it, 360-4.025
so the angle is 355.975°
now, the 3rd quadrant has another angle whose sine is negative, so... if we move from the 180° line down by 4.025, we end up at 184.025°
and those are the only two angles, because, on the 2nd and 1st quadrants, the sine is positive, so it wouldn't have an angle there
