Question

what is the value of a?

Explanation:

Step1: Use the property of isosceles triangle

In a triangle, if two angles are equal, then the sides opposite to them are equal. Here, \(\angle F=\angle H\), so the sides opposite to them \(HG = FG\).

Step2: Find the value of \(a\)

Since \(FG = 3\) and \(HG=a\), and \(HG = FG\) (from Step 1), then \(a = 3\).

Answer:

\(3\)
