Answer:
x = 20
Step-by-step explanation:
Diagonals bisect so you can set the two equal to each other
3x + 3 = 6x - 57
Solve:
3 = 3x - 57
60 = 3x
20 = x
Set 2x+3 and 6x-57 equal to each other since both halves of The diagonal are equal length therefore equal measurement
B. 4/8 = 5/10 = 1/2
I calculated it logically
Easy! The answer is B!
