  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.

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
