what is the value of $g$?

Explanation:

Step1: Find adjacent angle to g

First, calculate the angle supplementary to the sum of 73° and 85°. $\text{Adjacent angle} = 180^\circ - 73^\circ - 85^\circ = 22^\circ$

Step2: Relate to g (vertical angles)

Vertical angles are equal, so g equals the adjacent angle. $g = 22^\circ$

Answer:

$22^\circ$
