Answer:
BC = 3.7 units
Explanation:
Given:
From the figure ADBC,
AD = 3.7 units, AC = 4.1 units.
BA bisects DC perpendicularly.
The perpendicular bisector theorem states that:
"When a line bisects another line segment, then a point on the perpendicular bisector is equidistant from the two ends points of the given line segment".
Therefore, point B will be equidistant from point D and point C.
So, BD = BC
We have BD = 3.7 units. Therefore,
BC = BD
BC = 3.7 units.
So, the measure of the side BC is 3.7 units.
