angle N

Step-by-step explanation:

The order of the triangle names HAS to indicate which angles are congruent. First letters are congruent (D and M), second letters are congruent (E and N), and third are congruent (F and O). Also, the diagram shows that the triangles are reflections of each other. reflect one triangle onto the other, and you see that E and N overlap.

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

answer: -1
