In ΔCAB, if the measure of segment AB is 8 units and the measure of segment segment AC is 5 units, which of the following could be the measure of segment segment CB?

triangle CAB, point E is on segment AC between points A and C and point D is on segment BC between points B and C, creating segment ED

12 units
13 units
14 units
15 units

100 points for the right answer

12

Step-by-step explanation:

Since the two other sides are 8 and 5, then the third side will have to be in between 3 and 13. This is because 8-5 is 3, and 8+5 is 13. And there you have it.

12 Units

Step-by-step explanation:

I have taken the exam

look at photo

statement #3: proof- ang is congruent to ang ecd : angles are congruent.  

step-by-step explanation:

1: the missing angles in statement #3  

a.) acb  

reason- the reason why the answer is acb is because angle ecd and angle acb are both the same size *that's what the word congruent means this is really simple.  

2: the missing word in reason #3  

c.) vertical  

reason- the reason why the answer is vertical is because the angles in that diagram on figure 2 is slanted, which is vertical, and the e and a both lay on vertical lines. along with the other's, but e and a are the 2 main points you want to focus on. and c is kind of like your starting point, because c is for both angles, not just one.  

i hope that was and understanding.
