Question

in the figure below, ( ab = 18 ) and ( ac = 33 ). find ( bc ).

Explanation:

Step1: Use the segment addition postulate

From the figure, we know that \(AC = AB + BC\).

Step2: Solve for \(BC\)

Rearrange the formula to \(BC=AC - AB\). Substitute \(AB = 18\) and \(AC = 33\) into the formula: \(BC=33 - 18\).

$$BC = 33-18=15$$

Answer:

\(15\)
