Answer 1

$\huge\sf\underline{\underline{\pink{given}}}$

➝$\sf\green{sin57° = 0.84}$

$\huge\sf\underline{\underline{\green{solution}}}$,

➝$\sf\green{cos( 90°- A ) = sin A}$

$\huge\sf\underline{\underline{\red{AnsWeR}}}$

➝$\sf\green{cos(90° - 33° ) = 0.84}$

➝$\sf\green{cos 33° = 0.84}$

Answer 2

Answer:

cos 33° = 0.84

Step-by-step explanation:

sin (90° - β) = cos β

cos (90° - β) = sin β

~~~~~~~~~~~~~~

sin 57° = sin (90° - 33°) = cos 33° = 0.84
