Geometry!! Need help

Answer:
90° will be the measure,
Step-by-step explanation:
If the angles are congruent, it means that they are same, to find them out, we can be using a simple equation,
Let the angles be x,
x + x = 180° (Because, both the angles are equal as they are congruent)
=> 2x = 180°
=> x =( 180 / 2 )°
=> x = 90°
