Equations and Inequations
Equations and inequalities describe the relationship between two mathematical expressions.
Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
Question
Which equation can Jada use to find the value of x?
![### Understanding Tangent in Right Triangles
The image shows a right triangle with the sides labeled as follows:
- **Vertical side (pole)**: 3 units
- **Horizontal side**: 4 units
- **Hypotenuse (rope)**: Unlabeled but can be deduced using the Pythagorean theorem.
The angle adjacent to the vertical side and opposite the horizontal side is denoted as \( x^\circ \).
In a right triangle, the tangent of an angle \( x \) is defined as the ratio of the opposite side to the adjacent side. Hence, for the given triangle, the tangent would be:
\[ \tan(x) = \frac{\text{opposite side}}{\text{adjacent side}} = \frac{3}{4} \]
The question posed is to select the correct representation of the tangent function for the angle \( x \).
### Multiple-Choice Question
There are four options provided for identifying the correct trigonometric relationship:
- **Option A**: \( \tan(x) = \frac{3}{4} \)
- **Option B**: \( x = \tan\left( \frac{3}{4} \right) \)
- **Option C**: \( x = \tan\left( \frac{4}{3} \right) \)
- **Option D**: \( \tan(x) = \frac{4}{3} \)
From the earlier calculation:
\[ \tan(x) = \frac{3}{4} \]
Hence, the correct answer is **Option A**.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F8dd0c8f7-e44a-40b4-acd1-c48b9b4e0c83%2Fa7936794-b1cd-470b-bf7e-af1a09b9301f%2Fj5rh8tg_processed.jpeg&w=3840&q=75)
