An angle in an isosceles triangle has a measure of 20° what are the possible measures of the other angles

either 20* and 140*, or 80* and 80*

Step-by-step explanation:

80 and 80

Step-by-step explanation:

Since it also says 42 degrees, it would be 80 and 80

i found two solutions,   n = 2 • ± √3 = ± 3.4641

step-by-step explanation:

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.
