Question

find the value of g. g = ?° (2g)° 80°

Explanation:

Step1: Use angle - sum property

The sum of angles on a straight - line is 180°. So, \(80^{\circ}+2g = 180^{\circ}\).

Step2: Solve for \(g\)

Subtract 80° from both sides of the equation: \(2g=180^{\circ}- 80^{\circ}\), then \(2g = 100^{\circ}\). Divide both sides by 2: \(g=\frac{100^{\circ}}{2}\).

Answer:

\(g = 50^{\circ}\)
