A segment bisector is a geometric figure that divides the line segment exactly in half.
Vertical angles theorem states that vertical angles, angles that are opposite to each other and formed by two intersecting straight lines, are congruent.
distance = speed * time
the first bus speed = x
second bus = x - 12
the sum of distance = 765 miles
first distance = 6x
second distance = 6 (x -12)
6x + 6(x-12) = 765
x + x -12 = 127.5
2x = 139.5
x = 69.75 mi/h which is the faster bus
the second bus speed = 57.75 mi/h
The son is 8. I’m not sure if I’m right hope this helps
1 and 8 are because they are alternate exterior angles
1.25 or 1 1/4 however you want to look at it
