The answer would be 3 because both y points are equal so you look at the difference between the x points. The difference of 4 and 7 is 3. If this is right could I possibly have brainliest? Hope this helped!! :)
<h3>
First Method:</h3>
<u>Using cosine rule</u>:
<h3>
Second Method:</h3>
<u>First find XY using sine rule</u>:
Then use Pythagoras Theorem:
⇒ XY² + YZ² = XZ²
⇒ (6)² + YZ² = 12²
⇒ YZ² = 144 - 36
⇒ YZ = √108
⇒ YZ = 6√3
⇒ YZ = 10.4
<u>Answer-</u>
<em>The printer used </em><em>642 digits</em><em> to print all the pages in the book.</em>
<u>Solution-</u>
There are 250 pages numbered starting from 1 to 250.
The total number of digits would be the sum of digits of all single digits from 1 to 9, all double digits number from 10 to 99, and all triple digits number from 100 to 250.
There are 9 single digit numbers from 0 to 9, 90 double digit numbers from 10 to 99, and 151 triple digit numbers from 100 to 250.
So,
Therefore, the printer used 642 digits to print all the pages in the book.
Answer:
E 10 sqrt(2)
Step-by-step explanation:
If this is an isosceles triangle than AB = BC and AB = 10 so BC = 10
We want to us the Pythagorean theorem since it is a right triangle
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
10^2 + 10^2 = AC^2
100 + 100 = AC^2
200 = AC ^2
Take the square root of each side
sqrt(200) = sqrt( AC^2)
sqrt(100*2) = AC
We know sqrt(ab) = sqrt(a) sqrt(b)
sqrt(100) sqrt(2) = AC
10 sqrt(2) = AC
The sign needed to be added is x.
