Answer:
The four angles of a quadrilateral sum to 360 degrees.
If A and B are right angles then (2x+1) + 148 equal 180 degrees.
Therefore angle A = 32 degrees.

The answer to the question
Answer:
Option D. 36°
Step-by-step explanation:
we know that
The sum of the exterior angles of a polygon must be equal to 360 degrees
In a regular polygon all the exterior angles are congruent
so
To obtain the measure of each exterior angle divide 360 by the number of sides
In this problem the number of sides is 10
360/10=36°
