A Teacher wants to determine how many of all the 3th and 8th graders like soccer. The teacher uses the few minutes before the start of school to ask the the students if they like soccer. Do you think this will provide a random, unbiased sample for all the students? Is there anything that might not make this random, unbiased sample? Answer using complete sentences.

(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
