Answer:

15

Explanation:

  1. 28+4x+2=90 because the angle shows its 90 degrees and you need an equation for it.
  2. 30+4x=90 because you have to combine like terms which is the constant cause there is two of them so,you have to add 28 and 2.
  3. 4x=60 because you have to make 30 dissappear which it means you have to subtract in order to make it dissappear which it means 30-30. You'll have to do the same thing on the other side by subtracting from 90 which means 90-30=69.
  4. x=15 because your ganna have to divide on both sides in order to find the value of x.

Answer:

15

Explanation:

The little square in the corner means its a right triangle, so 90°. What we do here is subtract 28 from 90 to get 62, then we subtract the 2 in the equation from 62 to get 60. Then from there we divide 60 by 4 in order to get 15. I hope this helps you! :D
