Question

find the smallest angle of △qrs. assume that v is a positive number.

Explanation:

Step1: Recall the triangle side - angle relationship

In a triangle, the smallest angle is opposite the shortest side.

Step2: Compare the lengths of the sides

Given side lengths \(7v\) and \(18v\). Since \(v>0\), \(7v<18v\). The side opposite \(\angle S\) is \(7v\).

Answer:

\(\angle S\)
