Hey dear friend
The value of @is 37° because the the value of cos37° is 3/5 and when we multiply it with 20 we get 12 as a answer
perfectly fine pure correct answer
hope it helps you mark me as brainliest and follow me

but actually sin37=3/5=cos53
no this is wrong
sin 53 =3/5=cos 37
It's very simple construct a triangle sides 3,4,5 and mark the angle thita now one angle will be 90`,53` and 37` now by using sin and cos thita ratios we can find the angles sin37° = 3/5 = cos53
