  67.5 degrees

Step-by-step explanation:

The sum of measures of angles around a circle is 360°. The little square in the corner of the one angle indicates that is a right angle, 90°. So you have ...

  x + 3x + 90 = 360

  4x = 270 . . . . . . . . . subtract 90, collect terms

  x = 67.5 . . . . . . . . .  divide by 4

The value of x is 67.5 degrees.

If x is in radians, then it is 3π/8 radians.

choice b is correct
