In ∆ ABC above, which of the following must be true?
(A) r + s = x + y
(B) r + s = y – s
(C) r – s = x + y
(D) r – s = x – y
(E) r – s = y – x
[Reveal] Spoiler:
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
