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

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

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
