Triangle D F E is shown. Angle D E F is a right angle. The length of hypotenuse D F is 25, the length of E F is 15, and the length of D E is 20. Consider △DFE. What are the inputs or outputs of the following trigonometric ratios? Express the ratios in simplest terms.

sin( ) = 4/5

cos(F) =

tan(D) =

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.

i think it might be a but you might want a second opinion

21

jk it's 20

step-by-step explanation:

it should be a.

hope it
