Question

i) If sin? A + Cos? 15º = 1 then ​

Answer 1

Answer:

A=15⁰

make me brilliant and f-o-ll-o-w me

Answer 2

Answer:

Correct option is

51

We have,

sin(sin−151+cos−1x)=1

sin−151+cos−1x=sin−11

sin−151+cos−1x=2π

sin−151=2π−cos−1x

sin−151=sin−1x∴(sin−1x+cos−1x=2π)

x=51

Step-by-step explanation:
