as shown in the diagram below, a building casts a 72 foot shadow on the ground when the angle of elevation of the sun is 40 degrees. how tall is the building, to the nearest foot?

.

step-by-step explanation:

yes because they have the same amount of green and blur marbles.

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.
