Question

What is the value of X?
Sin64 degree= cos x
Enter your answer in the box.

Answer 1

sin 64° = cos x
cos x = sin 64°
x = cos⁻¹ (sin 64°)
x = 26°

Answer 2

x = 26° is the answer.

Explanation:

We have to find the value of x from the given equation.

sin 64° = cos x

since sin 64° = 0.8987

Therefore cos x = 0.8987

`x = cos^(-1)(0.8987) = 26`

x = 26°
