Answer:
9
Explanation:
9 root 2 = root 81 x root 2 = root 162
Root 162 = 12.7279220614
9^2 + b^2 = 12.7279220614^2
81 + b^2 = 162
b^2 = 81
Root both
B = 9

The answer is gonna be "D"
Area of rhombus = 1/2 * diagonal * diagonal
72 = 1/2 * AC * BD
Diagonals bisect each other in a rhombus so if EC is 8 then AC is 16
72 = 1/2 * 16 * x - 1
72 = 8(x-1)
9 = x-1
X = 10
Check
72 = 1/2 * 16 * 10-1
72 = 1/2 * 16 * 9
72 = 8 * 9
72=72
