Work out this please x

2240 m squared

Step-by-step explanation:

Trapezoid is A = ((a+b)/2) x h

so A = ((50+90)/2) x 32

A= 70 x 32

A= 2240 m squared

2 240 m²

Step-by-step explanation:

A = (b + B)×h/2

= (50m + 90m)×32m/2

= 140m×16m

= 2 240 m²

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.

the answer is "add 2y and y"

step-by-step explanation:

you need to collect the like terms first.
