Answer:

N = 3

Step-by-step explanation:

I don't know what the whole thing above is, but just disregard that.

All it is here is cross multiplication.

So 28N = 21 * 4

Multiply...

28N = 84

And divide each side by 28

N = 3

What in the world ? Why in the world above solve for n is two congruent triangles that appear to say a statement about them. For example, Triangle ABC is congruent to Triangle DEF. Ok idk why in the world the question has a symmetry and congruence question related to cross multiplication lol. N does equal 3 though
