Sagot :

To solve the given problem, let's follow the step-by-step process:

We are given that [tex]\(\sin(x) = \frac{7}{11}\)[/tex]. We need to find the value of [tex]\(\cos(90^\circ - x)\)[/tex].

1. Understand Relationship between Sine and Cosine:

From trigonometric identities, we know that:

[tex]\[ \cos(90^\circ - x) = \sin(x) \][/tex]

2. Substitute the Given Value:

We already have [tex]\(\sin(x) = \frac{7}{11}\)[/tex]. Therefore, substituting this into the identity:

[tex]\[ \cos(90^\circ - x) = \sin(x) = \frac{7}{11} \][/tex]

3. Conclude the Answer:

Thus, the value of [tex]\(\cos(90^\circ - x)\)[/tex] is [tex]\(\frac{7}{11}\)[/tex].

The correct answer is [tex]\( \boxed{\frac{7}{11}} \)[/tex].

Considering the provided options, the best answer is:

B. [tex]\(\frac{7}{11}\)[/tex]
