C can be found using pythagoras theorem. c2=a2+b2. Now, b is not given, but we know that cos(theta)=b/c=>b=c*cos(theta). Substituting b in the above relation, c2=a2+c2(cos(theta))^2=>c2=a2/(1-cos((theta))^2). c is the squareroot of c2. Hence c=sqrt(2/(1-cos((theta))^2))

A farmer owns about 960 acres of land. If his farm is square, what would be the length of each side in miles, to the nearest ten
OLEGan [10]

It is given in the question that

A farmer owns about 960 acres of land. If his farm is square.

First we convert acres to miles square, and the conversion expression is

1 acre=0.0015625 mi^2

Therefore,

960acres=960*0.0015625=1.5 mi^2

Let the side length of the square be x miles .

And the formula of area of square is

Area=side^2
\\
1.5=side^2
\\
side= \sqrt{1.5}=1.2 miles

2/5 - 1/3 (simplified if possible)
Kipish [7]

Answer:

1/15

Step-by-step explanation:

(1).   <em>Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD (Least Common Denominator). </em>

So lets do step one now, the LCD is 15 so we have to make both denominators agree on one number, so 15 is the number both denominators agree on.

Solve:

2*3/5*3 - 1*5/3*5

(2). <em>Complete the multiplication.</em>

6/15 - 5/15

(3). <em>The two fractions now have like denominators so you can subtract the numerators.</em>

6 - 5 / 15 - 15 = 1/15

*Pro tip:

<em>The denominator doesn't change and stays the same. So you don't </em>

<em>subtract the 15 by 15.</em>

(4). <em>Then you'll get the answer and then if you can simplify then simplify.</em>

<em />

The Answer is 1/15, and cannot be simplified.

So the answer is 1/15

Hope this helps!

Will the product of two numbers increase or decrease and by what percent if one of them is increased by 50%, and the other is de
Pavlova-9 [17]
:D

Let x be our first number and y be our second number.

The product of the two numbers will be xy.

Now let x be the one that increases by 50% and y be the one that decreases by 50%.

We can represent that by 1.5x and 0.5y, respectively.  If you are confused by that, let me explain.  If something increases by 50%, it becomes 1.5 times larger. So for x, that means 1.5x.
And if something decreases by 50%, it becomes 0.5 times smaller.  So for y, that means 0.5y.

Therefore we have 1.5x and 0.5y.  And the product of those two:

(1.5x) * (0.5y) = (3/2)x * (1/2)y = (3/4)xy

So our product is now (3/4)xy.

Comparing this answer to our original product of xy, we see that it is now only 3/4 as much or 75% of what it originally was.

Therefore, the product will DECREASE by 25%.
