Answer:
only 3) is true. EC is equidistant (the same distance) to BD
Step-by-step explanation:
since we have no coordinates or other specific distance information for the various points and lines, we can only confirm statements that must be true for any placement of the lines inside a circle with the described attributes.
the distance EC could be the same as CB, but if we move ED further up or down in the circle (still parallel to CB), we can easily see, that this is not a general case.
the same for CB and BD.
since CB and BD are airways parallel to each other, the symmetry principle of a circle requires that the distance of EC is airways equal to the distance of BD for all such possible pairs of parallel lines inside the circle.
the graph itself gives an example that the distance CB and the distance ED do not have to be the same. they can be for certain pairs of parallel lines in the circle, but not for all of them.
A + c = 3806....a = 3806 - c
19a + 9.5c = 55157
19(3806 - c) + 9.5c = 55157
72314 - 19c + 9.5c = 55157
-19c + 9.5c = 55157 - 72314
-9.5c = -17157
c = -17157/-9.5
c = 1806 <== # of children

Given: Parallelogram length = 11 cm triangle atop the parallelogram :
short leg = 7 cm : Right triangle inside the parallelogram :
long leg = 9cmArea of parallelogram =
base * heightA = 11cm * 9cmA = 99 cm²
Area of a triangle atop the parallelogram: A = ab/2A = (11cm * 7cm)/2A = 77 cm² / 2A = 38.5 cm²
Total area of the figure 99 cm² + 38.5 cm² = 137.5 cm²
I’m I think 79% but I’m probably way off
