Drag the tiles to the boxes to form correct pairs. Not all tiles will be used. Match the rectangles formed by the sets of points to their corresponding areas.
A(-9, 8), B(-5, 5), C(1, 13), D(-3, 16)
50 square units
E(30, 20), F(39, 29), G(49, 19), H(40, 10)
300 square units
I(-6, 2), J(2, 2), K(2, -8), L(-6, -8)
100 square units
M(5, 5), N(11, 5), O(11, -5), P(5, -5)
80 square units
Q(10, 0), R(15, 5), S(25, -5), T(20, -10)
U(0, 5), V(15, 20), W(25, 10), X(10, -5)

so, converting firstly the mixed fractions to improper fractions and then "adding".

it would be a on edgenuit y

the diagram below is your final answer

the answer is:

mean: 6

mad: 2.14

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.
