When a window is open, the temperature in a room falls 5ºF every 15 minutes. Before the window is opened, the temperature was 70ºF . Use the make a graph that shows the temperature of the room, T, after the window has been open for m minutes.

the answer is b.)

< 1=< 2

the answer is c)8

step-by-step explanaction:

step-by-step explanation:

the shape,the size and the distance

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.
