12 --> 23 = add 11
23 --> 34 = add 11
34 --> 45 = add 11

The arithmetic sequence is add 11. 

11 (15) = 165 mm
It starts at 12, so add 1, which is 166. 

So it is B. 

Hope this helps! I am sorry if this is wrong, but I tried!

What is the value of x?<br><br> Enter your answer in the box.<br><br> x =
Assoli18 [71]

Answer:

x = 5

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

x² + 12² = 13², so

x² + 144 = 169 ( subtract 144 from both sides )

x² = 25 ( take the square root of both sides )

x = \sqrt{25} = 5
