Cosx=sin34∘ cos x = sin 34 ∘ What is the value of x?

Short Answer 56

Remark

There are at least two ways of doing this. We can try them both.

Step One

Find the Sin (34)

Sin (34) = 0.5592

Step Two

Find Cos (x)

x = cos-1 (0.5592)

x = 56 degrees.

That's one way.

Another is just to do this

90 - 34 = 56

This is much simpler.

so x = 56

cos (56) = 0.5592

sin (34) = 0.5592

Cos (90-34) °=sin (34°) So Cos (56°) = Sin (34°)
