A rhombus has four 6-inch sides and two 120-degree angles. From one of the vertices of the obtuse angles, the two latitudes are

nikitadnepr [17]

Answer:

Area(A)=Area(C)= $9 in^{2}$

Area(B)= $13.2 in^{2}$

Step-by-step explanation:

We begin with finding the angles a and b that from the drawing attached you can see that a=b.

Now, the sum of the internal angles of a rhomboid is equal to 360 degrees, with that we have:

120+120+a+b=360

240+2a=360

2a=120

a=60=b

Next, in the image you can see that the lines coming from the angle at the top 120 degrees vertex, divide the opposite sides by half, thus making two triangles with one side of 6 in and another of 3 in.

We can say from the drawing as well:

Area(A)+Area(B)+Area(C)=Area(rhomboid)

But, we can also say that Area(A)=Area(C)

So, starting with Area(A)

Area(A)=Area(triangle)= $\frac{b*h}{2}$ = $\frac{6*3}{2}$ = $9 in^{2}$

We can then calculate the area B, a rhomboid, or better, take the Total area of the figure and subtract the area of the two triangles.

Area(B)=Area(rhomboid)-Area(A)-Area(C)

Area(rhomboid)=b*h where b=6in and h is the perpendicular distance from the base to the top.

$h=[tex]6*cos(30)=5.20in$ The 30 degrees come from: 120-30-60=30, since the latitudes split the 120 angle in two equal parts and one that is the half of the obtuse angle.

Area(rhomboid)=5.20*6= $31.2 in^{2}$

Area(B)=Area(rhomboid)-Area(A)-Area(C)= $31.2 in^{2}$ - $9 in^{2}$ - $9 in^{2}$ = $13.2 in^{2}$

Using the Babylonian method find √600 ???????????? √235.<br><br> how?

podryga [215]

Answer:

With the Babylonian method $\sqrt{600} \approx 24.494897$ and $\sqrt{235} \approx 15.329709$ .

Step-by-step explanation:

To find the square root of 600, do the following:

1. Make an initial guess: Because $\sqrt{576}=24$ and $\sqrt{625} =25$ you can start with $x_{0}=24$ as your initial guess.

2. Apply the formula:

$x_{1}=\frac{(x_{0}+\frac{x}{x_{0}})}{2}$ where $x=600$

$x_{1}=\frac{(24+\frac{600}{24})}{2}\\x_{1}=24.5$

The number $x_{1}$ is a better approximation to $\sqrt{600}$

3. Iterate until convergence:

For this apply the formula:

$x_{n+1}=\frac{(x_{n}+\frac{x}{x_{n}})}{2}$

Convergence is achieved when the digits of $x_{n+1}$ and $x_{n}$ agree to as many decimal places as you desire.

$x_{2}=\frac{(x_{1}+\frac{x}{x_{1}})}{2}\\x_{2}=\frac{(24.5+\frac{600}{24.5})}{2}\\x_{2}=24.494897$

$x_{3}=\frac{(x_{2}+\frac{x}{x_{2}})}{2}\\x_{3}=\frac{(24.494897+\frac{600}{24.494897})}{2}\\x_{3}=24.494897\\$

Because $x_{2}$ and $x_{3}$ agree to six decimal places. we can say that an estimate for $\sqrt{600} \approx 24.494897$ .

You can compare with the value that WolframAlpha gives you which is $\sqrt{600} \approx 24.49489742$ you can see that it agrees to six decimal places.
