The following figures are not drawn to scale but AB and CD are straight lines. Find x

x = 45

Step-by-step explanation:

The sum of the angles is 360 degrees

90+x+x+ 4x = 360

Combine like terms

90 +6x = 360

Subtract 90 from each side

6x = 360-90

6x = 270

Divide by 6

6x/6 = 270/6

x = 45

b. 153 students do not participate in sports and seventy-five 12th graders were surveyed

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.
