Respuesta :

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

Answer:

x = 26° is the answer.

Step-by-step 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

[tex]x = cos^{-1}(0.8987) = 26[/tex]

x = 26°
