Question

how many degrees are there on an angle which equal one fifth or its supplement​

Answer 1

Answer:

Step-by-step explanation:

Sum of an angle and its supplement = 180°

Let the angle be x and supplement be 5x

x + 5x = 180°

6x = 180°

x = 180/6

x = 30°

∴ The angle is 30° and the supplement is (30×5)° = 150°

Answer 2

Answer:

30° must be the correct answer.
