Let sides a/r, a, ar
(ar)² = (a)² + (a/r)²
r⁴ - r² - 1 = 0
r² = t
t² - t - 1 = 0
t = r² = (1 ± √5)/2
r = ±√(1 ± √5)/2
B

Both terms are in square root so values are real and positive.
So for maximum right hand term should be minimum i.e. zero
2a² - 1 - cos²x = 0
2a² = 1 + cos²x
Put
√sin²x + cos²x + 1
√2
