Answer:Segment A'B' is parallel to segment AB.
So, The length of segment AB is 7.5 units
The length of segment B'B is 3.5 units
Step-by-step explanation:
Segment A'B' is parallel to segment AB. Few sides of the triangle is given.
Apply basic proportionality theorem
When A'B' is parallel to segment AB then sides are proportional
Substitute the values
Now we find AB by making a proportion
The length of segment AB is 7.5 units
The length of segment B'B is 3.5 units
