Iwill mark the brainliest! i need now! ashton is constructing the bisector of mn¯¯¯¯¯¯¯.what should ashton do for his first step? a. use the straightedge to extend mn¯¯¯¯¯¯¯ in both directions. b. use the straightedge to draw a line that passes through point m. c. place the point of the compass on point m and draw an arc, making sure the width of the compass opening is greater than 12mn. d. place the point of the compass on point m and draw an arc, making sure the width of the compass opening is less than 12mn.

Question says that "Ashton is constructing the bisector of MN¯¯¯¯¯¯¯."

Now we need find about what should Ashton do for his first step?.

We know that to bisect any line say MN, we need to draw two arc from each end point M and N. Both arcs will intersect only when the width of the compass is more than half of the length of side MN. so that we we can join both intersection points to draw the perpendicular bisector.

Hence correct matching choice is C.

So the final answer is "C. Place the point of the compass on point M and draw an arc, making sure the width of the compass opening is greater than 12MN."

X=70

Step-by-step explanation:

70 + 75 + 35 =180

x + x+5 + x-35
