Question
Find b, x, and z each to two decimals. Find x and z, using only trig ratios to find the lengths.
![### Trigonometry Problem Solving
**Problem Statement:**
Given a right triangle with one of the angles measuring 32 degrees.
1. Label the sides and angles as follows:
- b: the length of the side adjacent to the 32-degree angle
- x: the length of the side opposite to the 32-degree angle
- z: the length of the hypotenuse
- The remaining angle (that isn't 90 degrees) is labeled as 32 degrees.
2. Assign the side lengths:
- The hypotenuse (z) forms the hypotenuse of the triangle.
- The length of the adjacent side (b) lies next to the 32-degree angle.
- The length of the opposite side (x) lies opposite to the 32-degree angle.
3. The remaining information provided is a right-angle denoted by a small square in the corner.
**Tasks:**
- Use trigonometric ratios (sine, cosine, and tangent) to find the following lengths each to two decimal places:
- b: Adjacent to the 32-degree angle.
- x: Opposite to the 32-degree angle.
- z: The hypotenuse of the triangle.
**Trigonometric Formulas:**
To find the length of each side, we can use the following formulas:
1. \( \cos(\theta) = \frac{\text{adjacent}}{\text{hypotenuse}} \)
2. \( \sin(\theta) = \frac{\text{opposite}}{\text{hypotenuse}} \)
3. \( \tan(\theta) = \frac{\text{opposite}}{\text{adjacent}} \)
Since angle \(\theta = 32^\circ\):
1. **To find the hypotenuse (z):**
- Use either the sine or cosine function depending on which side length you have.
2. **To find the adjacent side (b):**
- \( b = z \cdot \cos(32^\circ) \)
3. **To find the opposite side (x):**
- \( x = z \cdot \sin(32^\circ) \)
Note: Typically, if no initial side length is given, often a length ratio or unit measure may be assumed to apply trigonometric rules. If additional information such as initial side lengths is available, apply](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F0e9c998a-5af1-4bc2-b298-e1462b059995%2F44f7496b-2297-4a9a-b29d-3c9bb6252093%2F4d860pa_processed.jpeg&w=3840&q=75)
