1.) one side of a rectangle is 7 inches and the other side is x inches. what values of x will make the perimeter at most 26 inches? 2.) use the fact that the sum of the 3 angles in a triangle is 180 degree to answer this question. one angle in a triangle has a measure that is three times as large as the smallest angle. the measure of the third angle is 35 degree more than that of the smallest angle. find the measure of the each of the angles. i need the smallest angle, the middle angle and largest angle . you !

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.
