If sin x = cos y; write the relation between x and y, if both the angles x and y are acute.

sin x = cos y
cos y = sin (90° - y)
So, sin x = sin (90° - y)
⇒ x = 90° - y
⇒ x + y = 90°
Hence, the relation between x and y is x + y = 90°.

If sec A = cosec A and 0° ≤ A ≤ 90°, state the value of A.
If tan θ = cot θ and 0° ≤ θ ≤ 90°, state the value of θ.
If sin x = cos y, then x + y = 45°; write true or false.
sec θ. cot θ = cosec θ write true or false.
