Let's analyze the image to solve the questions. The problem involves a right triangle with a given height of 12 feet and a base of 15 feet. Based on the image, it seems like the questions ask about different aspects of this right triangle. Here's how to solve them:

### Step 1: Review the Triangle Properties
The triangle has the following dimensions:
- **Height** (vertical leg): 12 feet
- **Base** (horizontal leg): 15 feet
- **Hypotenuse**: Can be calculated using the Pythagorean theorem.

### Step 2: Calculate the Hypotenuse
The Pythagorean theorem states that for a right triangle:
\[
\text{Hypotenuse}^2 = \text{Height}^2 + \text{Base}^2
\]
\[
c^2 = 12^2 + 15^2
\]
\[
c^2 = 144 + 225 = 369
\]
\[
c = \sqrt{369} \approx 19.2 \text{ feet}
\]

### Now let's answer the questions a through d:

#### a) Find the length of the ramp (which is the hypotenuse of the triangle).
Using the Pythagorean theorem, as calculated:
\[
\text{Length of the ramp} = \sqrt{369} \approx 19.2 \text{ feet}
\]

#### b) Find the sine, cosine, and tangent of the angle \(\theta\) (the angle between the base and the hypotenuse).

- **Sine of \(\theta\)**:
\[
\sin(\theta) = \frac{\text{Opposite}}{\text{Hypotenuse}} = \frac{12}{19.2} \approx 0.625
\]

- **Cosine of \(\theta\)**:
\[
\cos(\theta) = \frac{\text{Adjacent}}{\text{Hypotenuse}} = \frac{15}{19.2} \approx 0.781
\]

- **Tangent of \(\theta\)**:
\[
\tan(\theta) = \frac{\text{Opposite}}{\text{Adjacent}} = \frac{12}{15} = 0.8
\]

#### c) If a person walks up the ramp, how many feet vertically will they have risen after walking 5 feet along the ramp?

To find the vertical rise, use the sine of the angle \(\theta\) calculated above:
\[
\text{Vertical rise} = 5 \times \sin(\theta) \approx 5 \times 0.625 = 3.125 \text{ feet}
\]

#### d) If the person walks all the way up the ramp, how many more feet would they have to walk to be 10 feet above the ground level?

First, determine the horizontal distance corresponding to a 10-foot rise:
\[
\text{If } \text{Vertical rise} = 10 \text{ feet, then: }
10 = \text{Length walked along the ramp} \times \sin(\theta)
\]
\[
\text{Length walked along the ramp} = \frac{10}{0.625} \approx 16 \text{ feet}
\]
The person will walk 16 feet to be 10 feet above ground level. Given that the ramp's total length is 19.2 feet, the additional distance they need to walk is:
\[
19.2 - 16 = 3.2 \text{ feet}
\]
