Describe and correct the error a student made in finding the midpoint of CD with C(-4,5) and D(-1,- 4).

Choose the correct answer below.

O A. The student used incorrect coordinates when calculating the midpoint.

O B. The student did not add the x- and y-coordinates when calculating the midpoint.

OC. The student did not divide the numerator and denominator by 2 when calculating the n

OD. The student swapped the x- and y-values when calculating the midpoint.

(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

same question do you know the answer
