Given m
|| n, find the value of x.
m
n
126°
(8x+6)

6

Step-by-step explanation:

since m is parallel to n, they both also have the same angles at the intersection with the crossing line.

the total angle on one side of a line is simply a half circle = 180 degrees (the angle of flipping over from laying flat in one direction of the line to laying flat in the other direction of the line).

so, the two angles of m with the intersecting line are

126 degrees and

(8x + 6) degrees.

and their sun must be 180.

126 + (8x+6) = 180

132 + 8x = 180

8x = 48

x = 6

the image of (6, 9) under a dilation is (4, 6). the scale factor is
