For lines a , c , and d , line c is parallel to line d and m ∠ 1 = 55 ° . Part A: For the given diagram, use the measure of ∠ 1 to find the measure of the remaining seven angles. Part B: In two or more complete sentences, explain the relationship between angle pairs a) ∠ 1 and ∠ 7 and b) ∠ 1 and ∠ 2 . in your explanation, include how you calculated each of the angle measures in the special angle pairs.

Part A:

1, 4, 5, and 8 = 55 degrees.

3, 2, 6, and 7 = 125 degrees.

Part B:

I know that angle 1 is 55 degrees so angle 7 would be 125.

I know that angle 1 is 55 and to get angle 2, both angles should add up to 180 so 180 - 55 is 125, that is how I find angle 2 = 125 degrees.

Step-by-step explanation:

This is what I wrote, I hope it helps and tell me if I am wrong but I think it is right.

Have a Meowgical day!

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.
