If cos x = sin y and cot (x - 40°) = tan (50° - y), then the value of x and y are:

x = 70°, y = 20°

x = 75°, y = 15°

x = 85°, y = 5°

x = 80°, y = 10°

x = 85°, y = 5°

cosx = siny
cosx = cos(90° - y)
x = 90° - y
x + y = 90° ...(i)

cot (x - 40°) = tan (50° - y)
cot (x - 40°) = cot (90° - 50° + y)
x - 40° = 40° + y
x - y = 80° ...(ii)
Solving (i) and (ii),
x = 85° and y = 5°
