Drag and drop the descriptions in the box that correctly classifies the angle pairs. you may use multiple responses in the boxes

1.→∠CEA and ∠CEF are Adjacent Angles.Two Angles are said to be Adjacent if there is one common ray between these two angles and non common ray lie on opposite side of common ray.

Here, CE is a common ray and AE and EF are non common rays.

2.→CD is a line.

→∠CEF+∠FED=180°---Angle in a Linear pair

→90°+∠FED=180°

→∠FED=180°-90°

→∠FED=90°

So, ∠FEB and ∠BED are Complementary.That is sum of these two angles is 90°.

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.

the answer is  

a.

28 ft2
