How do i explain how the distance on the number line and opposit numbers are related
strojnjashka [21]
Hey there!

The distance on a number line is the distance that a point is from 0.
For example, if you were looking at a number line and there was a point on the number 5, that point would be 5 units away from 0.

Opposite numbers are related because they are the same distance away from 0. For example -3 and 3 are both 3 units away from the number 0.

I hope this helped! :-)

GEOMETRY HELP WILL MARK BRAINLIEST
alisha [4.7K]

Answer:

x=8

z = 115

Step-by-step explanation:

65 and 13x - 39 are vertical angles so they are equal

65 = 13x - 39

Add 39 to each side

65+39 = 13x - 39+39

104 = 13x

Divide each side by 13

104/13 = 13x/13

8 =x

65 and z are supplementary angles because they form a straight line.  This means they add to 180

65+z = 180

Subtract 65 from each side

65+z-65 = 180-65

z = 115
