A photocopy of a polygon was reduced to 80% of its original size. The , the copy was again reduced to 80% of its size. What is the ratio of the corresponding sides of the second photocopy to the original?

(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

5 + 8 +7 + 4 + 0 +1 = 25

step-by-step explanation:

y= -2x+4, have a great day
