Question

Find the angle measure that makes the statement true. Sin 25° = Cos ____ °

Answer 1

Answer:

          sin 25° = cos 65°

Step-by-step explanation:

We have trigonometric result

                  sin θ = cos (90 -θ)

Here we asked to convert Sin 25°  in to cosine.

So,

          sin 25° = cos (90 -25) = cos 65°

          sin 25° = cos 65°

Answer 2

65. 

You simply have to put cos-1(sin(25))
