Answer:
C
Step-by-step explanation:
Let's break down the definitions.
Supplementary = degrees add up to 180
Vertical = share a common vertex
Complementary = degrees add up to 90
Adjacent = share a common side and vertex
Since the degrees add up to 90 and don't share a common side/vertex, the angles are complementary.

Answer:
They purchased 6 dozen eggs
Step-by-step explanation:
The total cost is the cost per dozen times the number of dozen purchased
total cost = 1.98 * n where n is the number of dozen
11.88 = 1.98n
Divide each side by 1.98
11.88/1.98 = 1.98/1.98 * n
6=n
They purchased 6 dozen eggs
BCD= 120 degrees. explanation: the 4 angles of a parallelogram must equal 360 degrees. so you add all 4 angles & get 6x. you then take that 6 & divide it from 360 (360/6) and get 60. therefore x=60. so then you just multiple BCD (2x) by 60 and you get 120 degrees
