Answer:

(A) 10°

Explanation:

You want the measures of the marked angles in the figure showing vertical angles marked (4x-8)° and (2x+1)°.

Vertical angles

The angles marked are vertical angles, which means they are congruent.

4x -8 = 2x +1

2x -8 = 1 . . . . . . . . subtract 2x

2x +1 = 10 . . . . . . . add 9

The angle measures are 10°, choice A.
