What is the distance between the points (-5,3) and (4,3)

Step-by-step explanation:

The formula of a distance between two points:

We have the points (-5, 3) and (4, 3). Substitute:

You can mark points in the coordinate system.

Look at the picture.

the 3rd on is correct

step-by-step explanation:

m∠5 + m∠3 = m∠1   is true.

m∠5 + m∠6 = 180 is true

m∠2 +m∠3 = m∠6   is true

m∠2 +m∠3 +m∠5 = 180   is true
