Question

1. choose the best answer. if $overline{ay}=4$, what is the measure of $overline{ac}$? $overline{ay}congoverline{yc}$

Explanation:

Step1: Identify equal - length segments

Given $\overline{AY}\cong\overline{YC}$ and $\overline{AY} = 4$, so $\overline{YC}=4$.

Step2: Calculate length of $\overline{AC}$

Since $\overline{AC}=\overline{AY}+\overline{YC}$, substituting the values we get $\overline{AC}=4 + 4$.
