I'm guessing that you want to calculate the middle horizontal line.
The upper left triangle on the left is a 45 45 90 triangle.
The hypotenuse is 12 and so the leg is 12 * (1/square root of 2)
leg = 12 *
<span>
<span>
<span>
0.7071067812
</span>
</span>
</span>
leg =
<span>
<span>
<span>
8.4852813742
</span>
</span>
</span>
So that means the line =
<span>
<span>
<span>
16.9705627485

Answer:
x=-22
Step-by-step explanation:
to get x by itself, subtract 12 from both sides: -22=x
Answer:
We need to find 5 + 10 + 15 + ... + 485 + 490 + 495. There are 99 numbers that are being added. To add this we can do 5 + 495, 10 + 490, 15 + 485 and so on. These pairs have a sum of 500 and since there are 98 / 2 = 49 pairs their sum is 500 * 49 = 24500. Since there is an odd number of numbers that are being added, there is one number that does not belong to a pair. That number is the 50th number in the list which is 50 * 5 = 250. Therefore the answer is 24500 + 250 = 24750.
