Select all systems of equations that have no solutions.
A:
{ y = 5 - 3 xy=-3x+4
B:
{ y = 4x - 14 y = 16 - 4
C:
{5x- 2 y = 3 10 x - 4y = 6
D:
{3 x + 7 y = 426 x + 14 y = 50
E:
{ y = 5 + 2xy = 5 x + 2
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.
