Answer:
25 degrees
Step-by-step explanation:
2x plus 310 degrees add up to a full circle: 360 degrees.
Therefore, 2x = 360 - 310, or 2x = 50, or x = 25 degrees
Answer:
Step-by-step explanation:
cos (x/2)=cos x+1
cos (x/2)=2cos ²(x/2)
2 cos²(x/2)-cos (x/2)=0
cos (x/2)[2 cos (x/2)-1]=0
cos (x/2)=0=cos π/2,cos (3π/2)=cos (2nπ+π/2),cos(2nπ+3π/2)
x/2=2nπ+π/2,2nπ+3π/2
x=4nπ+π,4nπ+3π
n=0,1,2,...
x=π,3π
or x=180°,540°,...
180°∈[0,360]
so x=180°
or
2cos(x/2)-1=0
cos (x/2)=1/2=cos60,cos (360-60)=cos 60,cos 300=cos (360n+60),cos (360n+300)
x/2=360n+60,360n+300
x=720n+120,720n+300
n=0,1,2,...
x=120,300,840,1020,...
only 120° and 300° ∈[0,360°]
Hence x=120°,180°,300°
To figure out the answer to this problem, you must first ask yourself this:
<span>
</span><span>How much is 126 of 700
</span> or
<span>What is 126 divded by 700
</span>
The answer is 0.18.
So, that means that 0.18 or 18 percent might be your answer.
Now, lets try 18 percent of 700, to see if we get 126.
<span>18% times 700
</span>
The anwer is 126.
SO:
$126 is 18 percent of 700.
18 percent of her sale is Destiny's commission.
