Answer:

D. 60°

Step-by-step explanation:

We are required,

To find the degree angle when [tex]\sin 30=\cos x[/tex].

Since, we know the relation [tex]\sin \theta=\cos (90-\theta)[/tex].

We have,

[tex]\sin \theta=\cos (90-\theta)\\\\\sin 30=\cos (90-30)\\\\\sin 30=\cos 60[/tex]

That is, x = 60°

Thus, the degree angle is 60° and option D is correct.
