Find the value of x that satisfies the given conditions. Then graph the line on a separate sheet of paper. The line containing (4,−2) and (x,−6) is perpendicular to the line containing (−2,−9) and (3,−4).

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.
