Please answer ASAP PART A:
James is setting up a fish tank. he’s buying a breed of goldfish that typically grow to be 12 inches long it is recommended that there will be 1 gallon of water for each inch of fish length in the tank
What is the ratio of fish to water?
PART B:
What size tank (in gallons) is needed for James to have 5 full grown goldfish?
How many full grown fish can go in a 40 gallon tank?
PART C:
James had so much success with his goldfish that he had to sell 1/3 of them to help with overcrowding. If he has 8 fish left in the tank, how many did he once have?

plz mark brainliest i took the test

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.
