Applying the segment addition theorem, the measure of segment BC is: 3.6 cm.
What is the Segment Addition Theorem?
According to the segment addition theorem, since all three points, A, B, and C are collinear, therefore, the following equation is true:
AB + BC = AC.
We are given the following:
AB = 4.7 cm
AC = 8.3 cm
BC = ?
Applying the segment addition theorem, we have the following equation:
4.7 + BC = 8.3 [according to the segment addition theorem]
Subtract 4.7 from each side of the equation
4.7 + BC - 4.7 = 8.3 - 4.7
BC = 3.6 cm
Thus, applying the segment addition theorem, the measure of segment BC is: 3.6 cm.
