Answer 1

Answer:

5°

Step-by-step explanation:

Let the angle be 'x'.

Then complement of the angle = (90 - x) and

  The supplement of the angle = (180 - x)

According to the question,

4 * (90 - x) = 2 * (180 - x) - 10

360 - 4x    =  360 - 2x -10

-4x + 2x   = 360 - 360 -10

    - 2x     = - 10

       x      = 5°
