Answer:
5 is the correct answer
Step-by-step explanation:
The length equals √123=11.09 inches
Therefore the statement "The length of the photo frame is between the 11 inches and 12 inches." is true.
Option D:

Solution:
Reflexive property of congruence:
<em>Reflexive property of congruence means the geometric figure is congruent to itself.</em>
Option A: If 
From the definition of reflexive property, it is not true.
This is transitive property of congruence triangles.
Therefore it is false.
Option B: 
From the definition of reflexive property, it is not true.
Therefore it is false.
Option C: 
From the definition of reflexive property, it is not true.
Therefore it is false.
Option D: 
Here, ΔKLM is congruent to itself.
This statement illustrates the reflexive property of congruence for triangles.
Therefore, it is true.
Hence option D is the correct answer.
Answer: z = -19.5
Step-by-step explanation:
-6.5 = z/3
-19.5 = z Multiply 3 to both sides
