Answer:
sin(D) = cos(F)
cos(D) = sin(F)
tan(D) = 1/tan(F) which means tan(F) = 1/tan(D)
Step-by-step explanation:
First it is important to know that the sine of an angle is the fraction of the opposite side over the hypotenuse side, while cosine is the adjacent over the hypotenuse and finally tangent is opposite over adjacent. You can't take the sine, cosine or tangent of the right angle like this though.
sine is o/h
cosine is a/h
tangent is o/a
So let's do each angle.
Keep in mind E is the right angle so we can't take any trig function of it with SOH CAH TOA so let's do D first.
D has an adjacent side of f since e is the hypotenuse, which leaves d as the opposite so lets go throught he trig functions.
sin(D) = d/e
cos(D) = f/e
tan(D) = d/f
Now let's do the same with F. d is adjacent, e is the hypotenuse and f is opposite.
sin(F) = f/e
cos(F) = d/e
tam(F) = f/d
Now, you can actually match them up
sin(D) = cos(F)
cos(D) = sin(F)
tan(D) = 1/tan(F) which means tan(F) = 1/tan(D)
And just looking at that we've answered the question. let me know if that doesn't make
Answer:
$70.59
Step-by-step explanation:
- 15% of $83.05 = 12.4575
- $83.05 - $12.4575 = $70.59
I hope this helps!
The area of square flake of gold is 
<h3><u>Solution:</u></h3>
Given that width of square flake of gold is 
millimeter
To find : Area of square flake
Since gold flake is in shape of square, we can use area of square formula
<em><u>The formula for area of square is given as:</u></em>
where "s" is the length of one side
Hence , the calculated area of flake is
All plots correctly show the range, 5–73.
The 1st, 2nd, and 4th choices correctly show the median, 54.
Of those, the 2nd and 4th choices correctly show the first quartile, 14.
Of those, only the 2nd choice correctly shows the third quartile, 61.
_____
There are an odd number of data points, so the middle one is the median. That value divides the remaining points in to two groups of 5. That number is also odd, so its median is the middle of that group. If we use x for the lower half and y for the upper half, you have
... (5 x 14 x x) 54 (y y 61 y 73)
