3. The difference between the complement of an angle and two times of its remainder is 1 / 5 of the horizontal angle Explain the process in detail

3. The difference between the complement of an angle and two times of its remainder is 1 / 5 of the horizontal angle Explain the process in detail

Let this angle be x, its complementary angle be 180-x, the remainder angle be 90-x, and the difference be 180 * 1 / 5, then the following formula can be obtained: 180-x-2 (90-x) = 180 * 1 / 5, x = 36
