Step-by-step explanation:
So since we know that <u><em>all the angles in a octagon add up to 1080 </em></u>we can make a equation for this question which is down below.
So adding all that up we get this down below.
To find x we subtract 815 from 1080 and we get this.
And finally we divide 265 and 3.
So x is 88 and one-third nit it can be in decimal form like this below.
This is rounded to the nearest hundredth

Answer:
36
Step-by-step explanation:
Let's let n be any number.
If we multiply n by 2, we get 2n. Since anything multiplied by 2 is even, 2n <em>must</em> be even. Therefore, let 2n be our first number.
So, the consecutive even number will be (2n+2) followed by (2n+4).
We know that their sum must be 114. Therefore, we can write the following equation:
Solve for n. Combine like terms on the left:
Subtract 6 from both sides:
Finally, divide both sides by 6. Therefore, the value of n is:
Therefore, our first even number is 2n or 2(18) which equates to 36.
And the consecutive even numbers will be 38 and 40.
So, the smallest of them, the first term, is 36.
