Amber measured the length of her yard by walking from one end of the yard to the other. she counted 44 steps assuming that each of her steps was 1/2 m in length, amber said the length of her yard was 44 * 1/2= 22. the actual length is 19m what is the percent error

is this a multiple choice question?

if so it's a and c

(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
