Sarah visited an art gallery and wanted to buy several paintings, but due to their cost, she decided to buy some postcards of the painting at a much lower cost. The postcards are 3 inches by 5 inches, which is 2/7 the size of the original painting

(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

step-by-step explanation:

tried on you are knowing that we can't leave the picture in the graph ok no problem now you need to send it in the question group
