Supplementary angles are angles that add up to 180 degrees. So you have to do 180-75 which equals 105 and then you have to do 105 divided by 5 which equals 21. So x=21

Answer:

21

Step-by-step explanation:

If the angles are supplementary, that means they add up to 180 degrees.

That means if we subtract 75 from 180, we get 105.

If we divide 105 by 5, we get 21.

That means 21 * 5 + 75 = 180

or

5(21) + 75 = 180

Hope this helps!
