Find the m∠cde, if m∠bac = 55° and ∠bca is a right angle. 35° 45° 55° 90°

Step-by-step explanation:

We have been given an image of two triangles.

Since segment AB is parallel to segment CD and segment BC is parallel to segment DE.

We can see that segment AE is transversal for our given triangles.

Since corresponding angles of two parallel formed by a transversal are always equal.

We can see that corresponds to angle .      

Let us find measure of angle ABC using angle sum property.

Therefore, measure of angle CDE is 35 degrees.

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.
