What complex number is represented on the graph?

4 − 5i
4 + 5i
5 − 4i
5 + 4i

5-4i

Step-by-step explanation:

On the real axis we move 5 units in the positive direction (to the right, that is why we have 5, not -5), and then on the imaginary axis we move 4 units in the negative direction (down, that is why we have -4i, and not +4i).

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.
