Which numbers are a distance of 3 units from 12 on a number line? select each correct answer. 3 15 0 9 −9 −15

15 and 9 are the correct answers.

Step-by-step explanation:

The numbers that are at a distance of 3 units from 12 on a number line are given as:

We will add 3 to 12 and also subtract 3 from 12 to get both numbers on the left side an right side on the number line.

So, the correct answers are 15 and 9.

  21.3

step-by-step explanation:

multiplying the given equation by c/sin(25°), we get

  c = 9/sin(25°) ≈ 21.2958 ≈ 21.3

we assume "c" is the length of ab, the side opposite angle c in triangle abc.
