No, it is an imaginary number.
Can't take the square root of a negative number without creating a method termed an imaginary number, which is the square root of -1 which they have used " i " to signify.
Then square root of -11.2 would be written Sqrt(11.2)i.  The Sqrt(11.2) = 3.3466
so the answer is 3.3466i

zalisa [80]

If x represents the number of hours Shelton worked, then the expression 10.25x shows how much Shelton is paid for these x hours ($10.25 for an hour).

After taxes, social security, and his health care plan were deducted he earned

10.25x - 0.21(10.25x).

This means that taxes, social security, and his health care plan form 21% (0.21 as decimal) from 10.25x.

Answer:

  • (4x -4)° +x° +(6x-3)° = 180°
  • J = 99°
  • K = 64°
  • L = 17°

Step-by-step explanation:

The relation that helps you write an equation for x is, "the sum of angles in a triangle is 180°."

__

<h3>equation</h3>

  (4x -4)° +x° +(6x -3)° = 180° . . . . . sum of angles in this triangle

<h3>solution for x</h3>

  11x -7 = 180 . . . . . . . divide by °, collect terms

  11x = 187 . . . . . . . . add 7

  x = 17 . . . . . . . . . divide by 11

<h3>angle values</h3>

  m∠J = (6x -3)° = (6(17) -3)° = 99°

  m∠K = (4x -4)° = (4(17) -4)° = 64°

  m∠L = x° = 17°
