Answer:
x = 20º
Step-by-step explanation:
we know that sin x = cos(90-x)
Hence
sin 30º = cos(90 - 30)º
sin 30º = cos 60º
hence sin 30º can be also written as cos 60º
Also, as given
sin 30º = cos(3x)
therefore
cos 60º = cos(3x)
as we have cos on both side then angle for both side will be same
60º = 3x
=> 60º / 3 = x
=> x = 20º
Then x = 20º is answer.

Step-by-step explanation:
x-2=4+x
1) x-2=-(4+x)
x-2=-4-x
x+x=-4+2
2x=-2
x=-2/2
x=-1
2) x-2=4+x
=0
