![**Educational Content: Algebraic Expression with Arccosine**
### Problem Statement
Use the figure to write the expression in algebraic form given \( y = \arccos(x) \), where \( 0 < y < \pi/2 \).
\[ \cos(y) = \] [Blank for Solution]
### Diagram Explanation
A right-angled triangle is depicted with:
- The hypotenuse labeled as \( 1 \).
- One angle labeled \( y \).
- The opposite side labeled \( \) [no label].
- The adjacent side labeled \( x \).
### Instructions
To solve the problem, use the trigonometric identity related to the cosine function in a right triangle. Given that:
- \( \cos(y) = \frac{\text{Adjacent side}}{\text{Hypotenuse}} \).
Fill in the blank using the information from the diagram and the trigonometric identity to find the algebraic expression.
### Optional Section
**Show My Work:**
Provide a step-by-step explanation or calculation to derive the algebraic expression for \( \cos(y) \) based on the given figure.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fe35298e5-10ed-452c-b18c-35d9ef29ce25%2Ff470802d-80f6-4b70-bc62-7c99c3217c70%2Fppvnnj_processed.jpeg&w=3840&q=75)
