True or false? a circle could be circumscribed about the quadrilateral below.

Which of the expressions (on the photo document i inserted) together represent all solutions to the following equation? 8cos(12x)+4=-4 *the answer should be in degrees.* > i would like for someone to explain the process to find the solutions for this.

Which inequality is equivalent to -3x < -12? x < 4 , x < -4 , x > 4, x > -4
