Question

triangle m is a scaled copy of triangle l
what is the value of a?

Explanation:

Step1: Use the property of scaled - copy triangles

Scaled - copy triangles have the same shape, so their corresponding angles are equal.

Step2: Identify the corresponding angle

In triangle \(L\), the angle opposite to the side with length \(3\) (the non - equal side in terms of side lengths among the two given sides of length \(3\)) is \(120^{\circ}\). In triangle \(M\), the angle \(a\) is the corresponding angle to the \(120^{\circ}\) angle in triangle \(L\) since the triangles are scaled copies.

Answer:

\(120\)
