In this triangle, what is the value of x?
enter your answer, rounded to the nearest tenth, in the box.
x = km

Step-by-step explanation:

Given the right triangle in the image, you need to remember the following identity:

Observe the triangle. You can identify that:

Then, knowing these values, you can substitute them into  :

Finally, you have to solve for "x".

Therefore, the value of "x" rounded to the nearest tenth is:

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.
