Answer:

i can see the actual question, what is it?

In right triangles one of the angles will always be 90 degrees.

So if you had a right triangle with one right angle, a number, and a number, they always have to add up to 90 degrees as well, because a triangle is always 180 degrees

so  

  • side a = 90
  • side b = x
  • side c = y
  • x + y = 90
  • x + y + 90 = 180
