Question

Find the measure of segment BC given that AB = 4.7cm and AC = 8.3cm A B T

Answer 1

3.6 cm

Explanation:

If point B lies on segment AC, then the segment sum theorem applies.

Application

AB +BC = AC . . . . . . . . . . the whole is the sum of the parts

4.7 cm + BC = 8.3 cm

BC = 3.6 cm . . . . . . . . . . . subtract 4.7 cm from both sides
