Question

plzz slove it its urgent​

Answer 1

Answer:

Step-by-step explanation:

Sin32° = Sin (90° - 58°) = Cos58°  (∵ Sin (90 - θ) = Cosθ)

Tan26° = Tan (90° - 64°) = Cot64° (∵ Tan(90 - θ) = Cotθ)

Cos12° = Cos(90° - 78°) = Sin78° (∵Cos(90 - θ) = Sinθ)

Now substitute the values in the question

Sin32°Sec58° + Tan26°Tan64° + Cos12° - Sin78°

= Cos58° * Sec58° + Cot64° *  Tan64° + Sin78° - Sin78°

= 1 + 1 + 0

= 2.
