Expression sin75^(@) +cos 65^(@) in terms of trigonometric ratios of angles between 0^(@) and 45^(@)

Check and discuss the above relations [sin (90^@ - x) = (AB) /(AC) = cos x cos (90^@ - x) = (BC)/(AC) = sin x tan (90^@ - x) = (AB)/(BC) = cot x cot(90^@ - x) = (BC)/(AB) = tan x , cosec(90^@ - x) = (AC)/(AB) = sec x , sec(90^@ - x) = (AC)/(BC) = cosec x] , in the case of angle between 0^@ and 90^@ , whether they hold for these angles or not ?So, sin(90^@ - A) = cosA
