TUV - ABC

32

Step-by-step explanation:

(I'm assuming that TU is x)

We can see in the picture that CA's length is 11 and that VT's length is 44, and since they are similar triangles, we can say that all sides on triangle TUV are four times those on triangle ABC. Now, since AB is 8, four times 8 is 32.

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.
