Answer
umm, wheres the question?
Step-by-step explanation:
I think the correct answer would be C. A validation of congruency between two polygons would be that if by applying rigid motions you can make them coincide. Two figures are said to be congruent if and only if these figures have the same shape and the same size. All of their sides and angles are the same. Rigid motion is a motion done to a figure that preserves distance or length. If all the rigid motions like rotation, reflection, translation and glide reflection are done and the figures are the same or the lengths are preserved, then the polygons should be congruent.

Step-by-step explanation: Because it is just like saying 6-3
Answer:
AC = 17.8
Explanation:
to figure out the length of AC, you want to put the values into the tangent function:
tan 64° = AC/8.7
Now to solve:
first swap them so you have AC/8.7 = tan 64°
Multiply both sides by 8.7 to get AC = 8.7 tan 64°
then calculate it
AC = 8.7 x 2.0503...
AC = 17.8376
AC = 17.8 (3 Significant Figures)
Expand the equation by multiplying it with itself: (x-3)*(x-3)
x^2 - 3x - 3x + 9 = 5
x^2 - 6x + 9 = 5
x^2 -6x +4 = 0
Since this is not part of the choices, try a different approach. Take the square root of both sides:
x - 3 = square root of 5
x - 3 = +/- 2.24
I guess this is the middle term which is incomplete. The first and last choices are not equivalent to the given equation.
