Help with segment addition postulate??

Question

Find RT if RS= 5 1/8 inches.

** There is a segment bisector in the middle.

Find UW if VW= 5/8 inches.

** There is also a segment bisector in the middle.

Answer 1

Segment Addition Postulate: if B is on a line segment between points A and C, AB + BC = AC

You haven't giving enough information to solve those. Does the segment bisector pass through point S on segment RT, i.e. is S the midpoint of RT? If it does, then RS = ST; RT = RS + ST; RT = 2 * RS; RT = 5 1/4.
