Question

if sin 33° = m, then find Cos 57° and tan 57°​

Answer 1

Answer:

cos 57° = m , tan 57° = root 1-m^2/m

Step-by-step explanation:

sin33° => sin (90°-57°) = m

=>cos 57° = m

We know that,

sin^2 57° + cos^2 57° = 1

=> sin 57° = root 1 - cos^2 57°

= root 1-m^2

Hence, tan 57° = sin57°/cos57°

= root 1-m^2/ m
