Question

what is the value of f?

Explanation:

Step1: Analyze the angle relationship

The larger angle \(78.7^{\circ}\) is composed of the smaller angle \(48.1^{\circ}\) and \(f\). So, we use subtraction.

Step2: Calculate \(f\)

\(f = 78.7^{\circ}-48.1^{\circ}\)
\(f = 30.6^{\circ}\)

Answer:

\(30.6\)
