A farmer wishes to grow a 100m? rectangular vegetable garden. He has only 30m barbed wire, so he fences three
sides of the rectangular garden letting the compound wall
of his house act as the fourth side fence. Answer the
following questions:
Find the quadratic equation taking into consideration breadth and length x m and y m
respectively.
Find the perimeter of the garden.

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.
