Answer:
a. 8 in
b. 9¾ in
Step-by-step explanation:
a. Given:
AC = 5 in
CB = 3 in
Since points A, C and P are collinear, therefore,
AC + CB = AB (segment addition postulate)
5 + 3 = AB (substitution)
8 = AB
AB = 8 in
b. Given:
AC = 6¼ in
CB = 3½ in
AC + CB = AB (segment addition postulate)
6¼ + 3½ = AB (substitution)
9¾ = AB
AB = 9¾ in
