Point r is at 2,1.2 and point t is at 2,2.5 on a coordinate grid. The distance between the two points is. .

  1.3

Step-by-step explanation:

The two points lie on the same vertical line (x=2), so the distance between them is the difference of their y-coordinates:

  2.5 - 1.2 = 1.3 . . . distance between the points

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
