What is a possible third side to a triangle with side lengths of 13 and 4?

The possible third side to a triangle is 12.

Given that,

Based on the above information, the calculation is as follows:

Here we use the pythagoras theorem.

= 12.37

= 12

10

Step-by-step explanation:

The sum of any two measurements must be greater than the other measurement.

13 + 4 > ?

10

10 + 4 > 13

10 + 13 > 4

So 10 would work.

Hope I helped :)

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.
