Answer: Option 'A' is correct.

Step-by-step explanation:

Since we have given that

√72-3×√12+√192

As we have

\sqrt{72}=6\sqrt{2}

\sqrt{12}=6\sqrt{2}

\sqrt{192}=8\sqrt{3}

So, our equation becomes

6\sqrt{2}-3\times 2\sqrt{3}+8\sqrt{3}\\\\=6\sqrt{2}-6\sqrt{3}+8\sqrt{3}\\\\=6\sqrt{2}+2\sqrt{3}

Hence, Option 'A' is correct.

How many hours is 3200 seconds <br><br> 3200 s =_____hrs
dezoksy [38]

Dividing by 3,600

1

Determine the number of seconds you have. This information should be given, or it should be a figure you calculated yourself.

For example, you might be converting 2,400 seconds into hours.

ivide the number of seconds by 3,600. Note that there are 3,600 seconds in one hour.[1] So, if you have more than 3,600 seconds, your conversion will be greater than  hour. If you have less than 3,600 seconds, your conversion will be a fraction of an hour.

3

Convert your decimal to minutes. This step is helpful if you are working with a number of seconds equal to less than an hour, so that you can gauge how long a certain decimal is. To convert the decimal to minutes, multiply it by 60.[2]

3200 seconds = 0.88888889 Hours

(rounded to 8 digits)

Which relationship is always true for the angles x, y, and z of triangle ABC?
noname [10]

Answer:

y + z = x

Step-by-step explanation:

Let's rename angle BAC to w. Now, we have four angles: w, x, y, and z. We know that w + y + z has to equal 180 degrees, because a triangle's three angels always adds up to 180 degrees. We also know that w + x equals 180 degrees, because they are on the same line. These two phrases are equal:

w + y + z = w + x

We can then cancel w on each side:

y + z = x

Hope this helps! :)
