Answer/Step-by-step explanation:
1. PN = 29
MN = 13
PM = ?
[tex] PN = PM + MN [/tex] (Segment addition postulate)
[tex] PN - MN = PM [/tex] (subtract MN from each side)
[tex] 29 - 13 = PM [/tex] (substitute)
[tex] 16 = PM [/tex]
[tex] PM = 16 cm [/tex]
2. PN = 34, MN = 19, PM = ?
[tex] PN = PM + MN [/tex] (sediment addition postulate)
[tex] PN - MN = PM [/tex] (subtract MN from each side)
[tex] 34 - 19 = PM [/tex] (substitute)
[tex] 15 = PM [/tex]
[tex] PM = 15 cm [/tex]
3. PM = 19, MN = 23, PN = ?
[tex] PN = PM + MN [/tex] (Segment addition postulate)
[tex] PN = 19 + 23 [/tex] (substitute)
[tex] PN = 42 cm [/tex]
4. MN = 82, PN = 105, PM = ?
[tex] PN = PM + MN [/tex] (segment addition postulate)
[tex] PN - MN = PM [/tex] (subtract MN from each side)
[tex] 105 - 82 = PM [/tex] (substitute)
[tex] 23 = PM [/tex]
[tex] PM = 23 cm [/tex]
5. PM = 100, MN = 100, PN = ?
[tex] PN = PM + MN [/tex] (Segment addition postulate)
[tex] PN = 100 + 100 [/tex] (substitute)
[tex] PN = 200 cm [/tex]
