When Marie solved a system using substitution, she got 0 = 0. What can Marie conclude? The system of equations does not have a solution. The work must be incorrect because it is not possible to get this equation. The solution to the system is (0, 0). The system of equations has infinitely many solutions.

Step-by-step explanation:

0 = 0 is the correct equation without any variables.

It means the initial equations will be correct for any value of the variables.

This brings us to the conclusion that the system has infinitely many solutions.

Correct choice is D

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
