Assuming you want to solve for x:

Make 15x and 15 add up to 180 in an equation since they form a straight line. A straight line is 180 degrees.

15x + 15 = 180

  • Subtract 15 from both sides.

15x = 165

  • Divide both sides by 15.

x = 11

15 + 15 + 15x + 15x = 180

30 + 30x = 180

30x = 150

x = 5
