Refer to the explanation.

We first note that #pi# radians is equal to #180# degrees. So the angles here are #pi/12=15^@,2/3pi=120^@#.

The remaining angle is therefore: #180^@-15^@-120^@=45^@#.

The complementary angle to this angle is: #90^@-45^@=45^@#.

The supplementary angle to this angle is: #180^@-45^@=135^@#.
