1. **Problem:** Find the six trigonometric function values of the specified angle given the triangle with angle 30° between side 18 (vertical) and side 24 (horizontal), right angle adjacent to side 24, angle at right angle labeled \(\theta\).
2. **Step 1: Identify sides relative to \(\theta\)**
- Opposite side to \(\theta\) is 18 (vertical side).
- Adjacent side to \(\theta\) is 24 (horizontal side).
- Hypotenuse \(c\) is found by Pythagoras theorem:
$$c = \sqrt{18^2 + 24^2} = \sqrt{324 + 576} = \sqrt{900} = 30$$
3. **Step 2: Write formulas for six trig functions:**
- \(\sin \theta = \frac{\text{opposite}}{\text{hypotenuse}}\)
- \(\cos \theta = \frac{\text{adjacent}}{\text{hypotenuse}}\)
- \(\tan \theta = \frac{\text{opposite}}{\text{adjacent}}\)
- \(\csc \theta = \frac{1}{\sin \theta} = \frac{\text{hypotenuse}}{\text{opposite}}\)
- \(\sec \theta = \frac{1}{\cos \theta} = \frac{\text{hypotenuse}}{\text{adjacent}}\)
- \(\cot \theta = \frac{1}{\tan \theta} = \frac{\text{adjacent}}{\text{opposite}}\)
4. **Step 3: Calculate each value:**
- \(\sin \theta = \frac{18}{30} = \frac{3}{5} = 0.6\)
- \(\cos \theta = \frac{24}{30} = \frac{4}{5} = 0.8\)
- \(\tan \theta = \frac{18}{24} = \frac{3}{4} = 0.75\)
- \(\csc \theta = \frac{30}{18} = \frac{5}{3} \approx 1.6667\)
- \(\sec \theta = \frac{30}{24} = \frac{5}{4} = 1.25\)
- \(\cot \theta = \frac{24}{18} = \frac{4}{3} \approx 1.3333\)
5. **Final answer:**
\[
\sin \theta = 0.6, \quad \cos \theta = 0.8, \quad \tan \theta = 0.75, \quad \csc \theta = 1.6667, \quad \sec \theta = 1.25, \quad \cot \theta = 1.3333
