30%÷100% = 0.30; $85×0.30= $25.50; 85 - 25.50= $59.50.
15%÷100% = 0.15; $59.5 ×0.15 =8.92; 59.50 - 8.92= $50.58
$50.58
I am assuming you mean 4/7 as the sine or cosine cannot be higher than 1.
Lets find <span>θ,
</span>
θ = [sin-1](4/7) = 34.85 °
But lets take into account that this value is the equivalent in Quadrant I.
If Θ lies in Quadrant II , then θ = 180 ° - 34.85 ° = 145.15 °
So cosθ = cos (145.15) = -0.821
5/6 all you do is divide by 5
