Based on the diagram, which expresses all possible lengths of segment AB?

AB = 25
27 81

Answers

Answer:B

Step-by-step explanation:

27 < AB < 81 expresses all possible lengths of segment AB

What is Inequality?

A relationship between two expressions or values that are not equal to each other is called 'inequality.

The sum of the lengths of any two sides of a triangle is greater than the length of the third side (Triangle Inequality Theorem)

So AC+BC>AB

27+54>AB

81>AB

AB<81

27+AB>54

AB>54-27

AB>27

54+AB>27

AB>-27

Hence, 27 < AB < 81 expresses all possible lengths of segment AB
