2. the following formula relates three quantities: force (f), mass (m), and acceleration (a). f = ma a. solve this equation for m. b. if the force is f = –30units and the acceleration is a = 6 units, find the mass, m. c. if the force is f = 30 units and the mass is m = 10 units, find the acceleration, a.

a. F=ma

Divide both sides by a.

F/a=m

The answer to a. is m=F/a.

b. -30/6=m=-5

m=-5

The answer to b. is m=-5.

c. 30=10a

Divide both sides by 10.

3=a

The answer to d. is a=3.

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.
