AC = ? Group of answer choices: 4, 8, 16, 6

Solution

The image shows two triangles, ABC\triangle ABC and ATS\triangle ATS, where ATS\triangle ATS is similar to ABC\triangle ABC. Given that AS=4AS = 4, and we are solving for ACAC, we rely on the properties of similar triangles.

Key Observations:

  1. ATSABC\triangle ATS \sim \triangle ABC (indicated by the equal angles and proportional sides).
  2. ACAC includes both segments ASAS and SCSC.
  3. The proportionality of sides holds:

ASAC=TSBC.\frac{AS}{AC} = \frac{TS}{BC}.

Analysis:

  • AS=4AS = 4: This is given.
  • TSTS and BCBC are marked with similar proportions.
  • Using similarity, AC=8AC = 8 because ACAC is double ASAS due to the given proportionality.

Answer:

8\boxed{8}
