Answer:

40

Step-by-step explanation:

Zirconium is the 40th element in the periodic table. It means its atomic number (the number of protons inside the nucleus) is 40. But atoms are electrically neutral: this means that their number of electrons matches the number of protons. Therefore, since the atom of zirconium has 40 protons, it also has 40 electrons.

Geometry picture added

X and Z equal 72
Y equals 108.

This is because y and 108° are vertex angles meaning they are both equal to each other. X is 72 because it’s form a supplementary angle with 108°. So what I did to find x is I subtracted 108 from 180 to get 72°. Then I know x and z are vertex angles meaning that z is also equal to 72°
