Find m< 4 in degrees

m < 4 = 120

Step-by-step explanation:

When two anlges are supplementary, their angle measures add up to 180, apply this knowledge here;

m<3 + m<4 = 180

60 + m<4 = 180

m<4 = 120

120

Step-by-step explanation:

m<3 is 60 and 180-60=120

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.

its 60

4 x 12 = 48

3 x 4 = 12

48 + 12 = 60
