30

Step-by-step explanation:

Let U be the total  number of students waiting in line to get student IDs, A represents the number of students from Indiana and B represents the number of students are freshmen.

Given : n(U)=100

n(A)=50

n(B)=200

Also,

The number of students are freshmen who are not from Indiana is given by :-

alright well the answers to your question is

2xy/9 hope this have a nice day : )

step-by-step explanation:

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.
