Answer:
$5.61
Step-by-step explanation:
we know that
At a dinner, the meal cost $22 and a sales tax of $1.87 was added to the bill.
so
using a proportion
Find out how much would the sales tax be on a $66 meal
Let
x ----> the amount of sales tax on a $66 meal
sine:<span> the trigonometric function that is equal to the ratio of the side opposite a given angle (in a right triangle) to the hypotenuse.
</span>cosine: the trigonometric function that is equal to the ratio of the side adjacent to an acute angle (in a right-angled triangle) to the hypotenuse.
tangent: <span>a straight line or plane that touches a curve or curved surface at a point, but if extended does not cross it at that point.</span>
I believe it is 1:6.
I hoped this helped :)
As far as I can tell, that is as far as the expression can be simplified :)
