How to find the value of y in the similar triangles ΔABC and ΔXYZ?

Solution

To solve for yy in this similar triangle problem, we need to understand the relationship between the triangles. Since ABCXYZ\triangle ABC \sim \triangle XYZ, we know that the corresponding sides are proportional.

The corresponding sides are:

  • ABAB corresponds to XYXY,
  • BCBC corresponds to XZXZ,
  • ACAC corresponds to YZYZ.

Given values:

  • AB=34AB = 34, AC=16AC = 16, and BC=30BC = 30 for ABC\triangle ABC,
  • XY=15XY = 15 and XZ=xXZ = x for XYZ\triangle XYZ.

We can set up a proportion using the corresponding sides:

ABXY=BCXZ=ACYZ\frac{AB}{XY} = \frac{BC}{XZ} = \frac{AC}{YZ}

To find YZYZ (which corresponds to ACAC), we use the proportion with ACAC and XYXY:

ABXY=ACYZ\frac{AB}{XY} = \frac{AC}{YZ}

Substitute the known values:

3415=16YZ\frac{34}{15} = \frac{16}{YZ}

Cross-multiply to solve for YZYZ:

34YZ=161534 \cdot YZ = 16 \cdot 15 34YZ=24034 \cdot YZ = 240 YZ=24034=7.0588YZ = \frac{240}{34} = 7.0588
