Consider parallelogram ABCD with diagonal BD. What values of x and y prove that the parallelogram is a square if CD=20, AD=8x−4,
and ∠CBD=4y−3?
a. X = 2, y = 12
b. X = 2, y = 23. 5
c. X = 3, y = 12
d. X = 3, y = 23. 5
1 answer:
Answer: C
Step-by-step explanation:
For the parallelogram to be a square, all sides must have equal measure and all angles must be right.
This means that CD=AD -> 20=8x-4 -> 24=8x -> x=3
And 4y-3=45 -> 4y=48 -> y=12
