This is an arithmetic sequence, since it's pattern is +4.
n1 = 1
d = 4
n = 1 + (n-1)(4) <-------------- This is the formula for the nth term of the sequence.
its the first one
Step-by-step explanation:
because per pertains to to x
9/11 is rounded to 1. It rounds up because 9 is higher than 5, which is the middle of 11.
I got an answer of 58.
Subtract 10 from the side length of 24 to get 14.
And use the side length of 5 to find another side length that also equals 5.
In total all your side lengths would be 10,5,5,24,14. And all of them together to arrive at an answer of 58.
The answer is 132° because there angle CDE is 87° so you know it's more of that. And, 264° is way too wide.
