Question
HIJK is a rectangle. Find the value of x and the length of each diagonal

Transcribed Image Text:### Problem 13
**Rectangle HIJK**
*Find the value of \( x \) and the length of each diagonal if \( HJ = 3x^3 - 7x - 4 \) and \( IK = x^2 - 6x - 1 \).*
- **Diagram:** The rectangle is labeled as HIJK with \( H \) at the top left, \( I \) at the top right, \( K \) at the bottom left, and \( J \) at the bottom right.
- **Equations:**
- \( x = \) __________
- \( HJ = \) __________
- \( IK = \) __________
### Problem 14
*Find the perimeter and area of each figure. Give EXACT answers in simplest radical form, if needed.*
- **Diagram:** A square with a diagonal and one side marked as 7 inches.
- **Measurements:**
- **Side length =** __________
- **Perimeter =** __________
- **Area =** __________

Transcribed Image Text:**Worksheet on Geometry: Rhombus and Rectangle Problems**
### Part A: Rhombus
Given that **ABCD is a rhombus**, the following measures need to be found. Also, state the theorem or definition that supports each statement:
1. **AB = ___________**
- **Why?** (Statement and explanation needed)
2. **m∠ABC = ___________**
- **Why?** (Statement and explanation needed)
*Diagram Description:*
In the diagram, quadrilateral ABCD is labeled with lines and equations assigned to its sides and angles. Angles and sides are represented using algebraic expressions, for instance, *4x + 15* and *(xy - 1)°*.
### Part B: Rectangle
Rectangle **HIJK** Problem:
- **Objective**: Find the value of x and the length of each diagonal.
- If **HJ = 3x² - 7x - 4** and **IK = x² - 6x - 1**, solve for the following:
- **x = ___________**
- **HJ = ___________**
- **IK = ___________**
*Diagram Description:*
A rectangle labeled as HIJK is shown. The task requires using given quadratic equations representing the diagonals to solve for specific values.
**Instructions:**
- Provide exact answers in simplest radical form, if necessary.
- Use applicable geometric theorems and definitions to justify your solutions.
