Which of the following could be the ratio of the length of the longer leg of a 30-60-90 triangle to the length of its hypotenuse ?

Step-by-step explanation:

Please share the answer choices next time.

The simplest diagram of a 30-60-90 triangle indicates leg lengths of 1 and √3 and hypotenuse 2.  Thus, the desired ratio is √3/2.  This is the sine of 60° and also the cosine of 30°

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

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.
