Use the formula A=s? to find each side length. To solve, take the square root of both sides of
the equation.
A=52
25 = 32
Because 52 = 5 x 5 = 25
125 = 52
and (-5)2 = -5 X-5 = 25,
+5 = 5 s = 5 and s= -5, or s = +5.
Hei

I don't get this at all these math questions

answer:   c ?

step-by-step explanation:

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.
