Question

please solve this trigonometry question and give step by step explanation​

Answer 1

Answer:

$\large\mathbf\green{ANSWER \: :}$

We know that, cos A = sin( 90° - A)

So, sin (50°+ x°) = sin (90° - 30°)

sin (50° + x°) = sin 60°

50° + x° = 60°

x° = 60° - 50°

x° = 10°

$Hence \: the \: value \: of \: x \: is \: 10°.$

Answer 2

We know that, cos A = sin( 90° - A)

So, sin (50°+ x°) = sin (90° - 30°)

sin (50° + x°) = sin 60°

50° + x° = 60°

x° = 60° - 50°

x° = 10°

Hence ,
