Question

sin 765° ka maan gyat karo

Answer 1

answer of sin 765 is =0.707106781

Answer 2

Let x be any angle. We know that sin(360°+x) = sin x°.

We can denote sin 765° as sin (360°+some angle).

sin 765° = sin (765°-360°) = sin 405°, and seeing that 405° is > 360°, we can repeat the step above, hence, sin 405° = sin (405°-360°) = sin 45°

sin 45° is a standard value, which equals 1/√2.

Hope I helped!
