Question

If sin30°= cos x then cos x? ​

Answer 1

Answer:

sin 30 = 1/2

cos 60 is also equal to 1/2

sin 30 = cos x

cos x =1/2

cos x = cos 60

x=60

Answer 2

$Given \: sin 30\degree = cos x$

$\implies cos ( 90 \degree - 30\degree) = cos x$

$\boxed { \pink { Since, sin \theta = cos ( 90 \degree - \theta ) }}$

$\implies cos 60\degree = cos x$

$\implies 60\degree = x$

Therefore.,

$\red{ Value \:of \:x } \green { = 60\degree }$
