Aconsistent system of equations is a system with a. the same line b. parallel lines c. intersecting lines and lines that have the same slope d. intersecting lines and lines that have the same equation

A system of two linear equations can have unique solution, infinite number of solutions, or no solution. Systems of equations can be classified by the number of solutions.

Therefore, consistent system of equations has one solution (intersecting lines) or infinitely many solutions (the same line).

correct choice is D.

60

step-by-step explanation:

every triangle measures a total of 120 degrees. you have to find angle c. we know that isosceles triangles angles are equal. 60 degrees plus 60 degrees gives you 120.
