Question

Triangle A B C is shown. Side A C has a length of 27. Side C B has a length of 54.

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

AB = 25
27 < AB < 81
AB = 85
AB< 27 or AB > 81

Answer 1

Based on the information given, the possible lengths of segment AB can be determined using the Triangle Inequality Theorem. This theorem states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side. In this case, we can apply the theorem to sides AC and CB to find the possible range of values for side AB.

Since AC has a length of 27 and CB has a length of 54, we can write two inequalities based on the Triangle Inequality Theorem:

AB + 27 > 54 AB + 54 > 27

Solving each inequality for AB, we get:

AB > 27 AB > -27

Since the length of a side of a triangle must be positive, we can disregard the second inequality. Therefore, the possible range of values for side AB is AB > 27.

However, it’s important to note that you mentioned a diagram in your message but did not provide it. Without seeing the diagram, I cannot determine if there are any additional constraints on the length of side AB.

Answer 2

Explanation:

Based on the diagram and the given lengths of sides AC and CB, we can use the triangle inequality theorem to determine the possible lengths of side AB.

According to the theorem, the sum of the lengths of any two sides of a triangle must be greater than the length of the third side. Therefore:

AC + CB > AB

27 + 54 > AB

81 > AB

Also, using the same theorem, we can see that:

AB + AC > CB

AB + 27 > 54

AB > 54 - 27

AB > 27

Therefore, we have:

27 < AB < 81

So, the answer is: 27 < AB < 81
