Pls answer ok i’m dumb bye answer in a hour

Elements are arranged in the periodic table based on various patterns. For example, elements found in the rows near the top

A.  

all have the same atomic number.

B.  

have the same atomic numbers as the elements in the rows near the bottom.

C.  

have higher atomic numbers than the elements in the rows near the bottom.

D.  

have lower atomic numbers than the elements in the rows near the bottom.

i am not sure

congruent segments

step-by-step explanation:

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
