The correct answer for this question is letter "<span>D. (x) / (sqrt (1+x^2))."

Make a triangle. yes a triangle. label "opposite" side x and adjacent side 1 since the tangent is x = x/1
use pythatoras to find the hypotenuse which will be
square root (1 + x^2)
then
<span>sin(ta<span>n<span>−1</span></span>(x)<span>) = x / (square root (1 + x^2))
</span></span>
that being opposite over hypotenuse
and by the same triangle
<span>cos(ta<span>n<span>−1</span></span>(x)) = </span>x / (square root (1 + x^2))
Answer: 180 and 900
Step-by-step explanation:
1500/ 100 x 12 = 180
5 years; 180x 5 = 900
The Answer Will Be 1.1205 x 10 To The 5th Power.
300-3x=33
Subtract 300 on both sides.
-3x=-273
Divide both sides by -3.
x=91
I hope this helps!
