Question

1. what is the sum of f° + g°?

Explanation:

Step1: Use the property of adjacent angles on a straight line

Adjacent angles on a straight line sum to \(180^{\circ}\). For the angle \(60^{\circ}\) and \(g^{\circ}\), we have \(60 + g=180\), so \(g = 180 - 60=120^{\circ}\).

Step2: Calculate \(f + g\)

Since \(f\) and \(g\) are adjacent angles on a straight line, \(f+g = 180^{\circ}\).

Answer:

\(180^{\circ}\)
