Circle D is shown. Line segment F E goes through point D. Line segment C D is shown. Line segment G H goes from one side of the circle to the other side. Line segment A B is outside of the circle and intersects the circle at point B. In circle D, which is tangent to the circle? Line G H Line segment A B CD EF

The line that is tangent to the circle D is: line segment AB.

From the image of circle D as shown in the second diagram, line segment AB touches the curve of circle D at point B.

Therefore, the line that is tangent to the circle D is: line segment AB.

A tangent line is a line on the outside of the circle that only touches it at one point.

The tangent line would be Line Segment AB

step-by-step explanation:

polynomial long division :

3.2     polynomial long division

dividing :   x4+5x3-4x2-8x+6

                              ("dividend")

by         :     x-1     ("divisor")

dividend     x4   +   5x3   -   4x2   -   8x   +   6

- divisor   * x3     x4   -   x3            

remainder         6x3   -   4x2   -   8x   +   6

- divisor   * 6x2         6x3   -   6x2        

remainder             2x2   -   8x   +   6

- divisor   * 2x1             2x2   -   2x    

remainder               -   6x   +   6

- divisor   * -6x0               -   6x   +   6

remainder                     0

quotient :   x3+6x2+2x-6   remainder:   0

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
