Question #16769

line segment ab =6 line segment cd=5 what is line segment ad ?

Expert's answer

Let's assign operator |AB| as a length of a segment AB. Then

|ad| = |ab| + |bc| + |cd| = 6 + |bc| + 5 = 11 + |bc|,

where |bc| is the unknown lenghth of a segment bc.

|ad| = |ab| + |bc| + |cd| = 6 + |bc| + 5 = 11 + |bc|,

where |bc| is the unknown lenghth of a segment bc.
