I think it’s 180 because either straight across it’s a straight line so 180 and half of a circles 360 degree is 180

Answer:  180

===========================================================

Explanation:

Angle PAQ is 90 degrees as the square marker indicates. The adjacent angle RAQ is also 90 degrees.

So overall, central angle PAR is 90+90 = 180 degrees. Arc PQR is 180 degrees which is a semicircle.
