2.4.16 Let:
U= {a, b,c, d,e, f,g, h}
A = {b, d,e}
B = {a, d,e}
C={a, c,f, g,h}
Find the set (AnB) U (Anc).
Select the correct choice below and if necessary fi

(A⋂B) U (A⋂C) = {d, e}

Step-by-step explanation:

U= {a,b,c,d,e,f,g,h}

A = {b,d,e}

B = {a,d,e}

C={a,c,f,g,h}

=> A⋂B = {d,e}

=> A⋂C = ∅

=> (A⋂B) U (A⋂C) = {d, e}

x/3-10=8

x/3=18

x=48

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.
