Given:
The last year sales = $288,000,000
Company increased its sales from last year to this year by 34%.
To find:
The this year's sales to the nearest million dollars.
Solution:
We have,
The last year sales = $288 million
The company increased its sales from last year to this year by 34%. So,
This year's sales 



Therefore, this year's sales were 386 million dollars or $386,000,000.
Using trigonometric relations, we will see that:
sin(θ ) = -0.8
<h3>
How to get the sine of the angle?</h3>
For any point (x, y), the angle between the positive x-axis and the ray that connects the origin with the point (x, y) is:
θ = Atan(y/x)
In this case, the point is (3, -4), then the angle is:
θ = Atan(-4/3) = -53.13°
Then the sine of theta is:
sin(θ = -53.13°) = -0.8
