Pairs of consecutive angles of a parallelogram are congruent. a. always b. sometimes c. never

B. Sometimes  

Step-by-step explanation:

Opposite angles of a parallelogram are always congruent, and consecutive angles are always supplementary (first image).

However, consecutive angles can be congruent if they are each 90°. The parallelogram is then a rectangle or a square (second image).

Thus, pairs of consecutive angles of a parallelogram are sometimes congruent.  

d is the correct answer

step-by-step explanation:

x= 8 because 3x = 3 * 8, and 3*8 = 24

if the pizza is divided equally into 2 equal halves then you would get
