Answer:

g = 60°

Explanation:

You want the measure of the marked remote interior angle of a triangle with exterior angle 130° and the other remote interior angle marked 70°.

Exterior angle

The exterior angle is equal to the sum of the remote interior angles:

70° +g = 130°

g = 60° . . . . . . . . . subtract 70°
