Question

triangle x is a scaled copy of triangle w. triangle w has sides labeled 15 and 25. triangle x has a side labeled y and a side labeled 20. the question asks: what is the value of y? there is a submit button and a work it out section with links to help topics like solve one - step multiplication and division equations with decimals and add, subtract, multiply, or divide two decimals.

Explanation:

Step1: Find the scale factor

Since triangle X is a scaled copy of triangle W, the ratio of corresponding sides is equal. The side of length 25 in triangle W corresponds to the side of length 20 in triangle X. So the scale factor \( k \) is \( \frac{20}{25}=\frac{4}{5} \).

Step2: Calculate \( y \)

The side of length 15 in triangle W corresponds to side \( y \) in triangle X. So \( y = 15\times\frac{4}{5} \).
\( y = 12 \)

Answer:

12
