Hello there!
To get from one number to the answer you really want, just take the absolute value! That is, to find the distance between any two real numbers: subtract them in any order.
For example: -4+5
On a numberline you start from zero, and jump to -4. Then you add 5 to the right giving you the answer.

35.89 + 43.65 = 79.54
<u>650 cannonballs
</u>
Explanation step by step:
layer 12 is 12 ^ 2
<u>The formula is:
</u>
n * (n + 1) * (2n + 1) / 6
n = 12
12 (12 + 1) (2 * 12 + 1) / 6
12 * 13 * 25/6 =
650
<u>There are 650 cannonballs in this pyramid.</u>
Answer:
<em>∠6 = 78°.</em>
Step-by-step explanation:
<em>∠3 = 78°</em>
<em>∠2 and ∠3 are vertical angles, => ∠2 = ∠3 = 78°.</em>
<em>∠2 and ∠6 are corresponding angles, => ∠6 = 78°.</em>
In order to know that, you need to divide 28 from 126
It would be:126/28 = 4.5
So, your final answer is 4.5
Hope this helps!
