Question

1. what values of y and z make (\triangle abccong\triangle fde)?

Explanation:

Step1: Use the property of congruent triangles

Since \(\triangle ABC\cong\triangle DFE\), corresponding sides are equal.

• For side \(y\): \(y\) corresponds to \(EF\). Given \(EF = 15\), so \(y=15\).
• For side \(z\): \(z\) corresponds to \(AB\). Given \(AB = 45\), so \(z = 45\).

Answer:

\(y = 15\), \(z=45\)
