Question

find the value of g. g = ?° (2g)° 80°

Explanation:

Step1: Use vertical - angle property

Vertical angles are equal. The angle with measure $(2g)^{\circ}$ and the angle with measure $80^{\circ}$ are vertical angles. So, $2g = 80$.

Step2: Solve for g

Divide both sides of the equation $2g = 80$ by 2. We get $g=\frac{80}{2}$.

Answer:

$40$
