*Visible Confusion*
Two triangles are shown to be congruent by identifying a combination of translations, rotations, or reflections that move one figure onto the other. If ΔMAP ≅ ΔCAR, which angle must be congruent to ∠ARC? Why?

Angle ARC is equal to Angle APM

Step-by-step explanation:

You can see above three scenarios of creating Triangle MAP & CAR. In all of the scenarios ARC & APM come in the same position. So as Triangle MAP & CAR are congruent then Angle ARC & APM are equal.

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

it is x equals 3   plese mark me really need it
