Question

question 2 (multiple choice worth 1 points) (03 05r mc) δaxy is similar to δabc. diagram of triangle abc with point x on ab and point y on ac, forming triangle axy which of the following expressions could be used to determine the length of segment ab? options: ( ab = ax cdot \frac{ac}{ay} ), ( ab = ax cdot \frac{ay}{ac} ), ( ab = ay ), ( ab = ax )

Explanation:

Step1: Recall Similar Triangles Property

For similar triangles \(\triangle AXY \sim \triangle ABC\), the corresponding sides are proportional. So, \(\frac{AX}{AB}=\frac{AY}{AC}\).

Step2: Solve for \(AB\)

From \(\frac{AX}{AB}=\frac{AY}{AC}\), cross - multiply to get \(AB\times AY = AX\times AC\). Then, divide both sides by \(AY\) to obtain \(AB = AX\times\frac{AC}{AY}\).

Answer:

\(AB = AX\cdot\frac{AC}{AY}\) (the first option among the given choices)
