As per the given information in the above triangle, we can see that:
r + x = 90
s + y = 90
So let's equate both the equations.
r + x = s + y = 90
r + x = s + y
r - s = y - x
Hence E - (E) r – s = y – x

We can create the following equation:
r + x + 90 = s + y + 90
r + x = s + y
r - s = y - x
Answer: E
