Answer: the answer is choice b which is 0 .
Step-by-step explanation: Any irregular quadrilateral has zero lines of symmetry because the sides are not equal so they won't form equivalent sides . This shape or quadrilateral can't be divided to lines of symmetry as the sides won't be equal . HOPE IT HELPS YOU BUDDY .PLEASE GIVE BRAINLIEST .THANKS .
Answer:
The coordinates of C(22/3, 7)
Step-by-step explanation:
Partitioning between two points A and B in the ratio a:b.
The x-coordinate of the point of partition C is found at
XC = XA*(b/(a+b)+XB(a/(a+b) ..............(1)
Similarly, the x-coordinate of the point of partition is found at
YC = YA*(b/(a+b)+YB(a/(a+b)...............(2)
Given A(8,8), B(4,2), partition ratio of A:B = 1:5,
substitute in (1)
XC = 8*5/6+4*1/6 = 44/6 = 22/3
YC = 8*5/6 + 2*1/6 = 42/6 = 7
