What is the value of x? sin 49° = cos x

x=41

Sin, cos and tan are part of the trigonometric function. Sin is calculated from opposite/hypotenuse, while cos is calculated from adjacent/hypotenuse.
There is some formula that can be derived from the equation. One of them is sin (90-x)= cos x
If you use it, the calculation would be:
sin 49° = cos x
sin 49= sin (90-x)
49= 90-x
x= 90-49= 41
