To solve this problem, we need to find two things:

1. The perpendicular height (h) that the car rose.
2. The angle of elevation (θ) of the slope.

### Step 1: Calculate the Perpendicular Height

The slope of $$ \frac{1}{8} $$ means that for every 8 units of horizontal distance, the vertical height increases by 1 unit.

Given that the car rides a distance of 100 m along the slope, we can use the slope ratio to find the height:

$$
\text{slope} = \frac{\text{height}}{\text{horizontal distance}} = \frac{1}{8}
$$

Let $$ d $$ be the horizontal distance. The relationship can be expressed as:

$$
h = \frac{1}{8} \cdot d
$$

To find $$ d $$, we can use the Pythagorean theorem, where the slope distance (100 m) is the hypotenuse:

$$
d^2 + h^2 = 100^2
$$

Substituting $$ h $$ into the equation gives us:

$$
d^2 + \left(\frac{1}{8}d\right)^2 = 100^2
$$

### Step 2: Solve for $$ d $$

Let's simplify and solve for $$ d $$:

$$
d^2 + \frac{1}{64}d^2 = 10000
$$

Combining the terms:

$$
\left(1 + \frac{1}{64}\right)d^2 = 10000
$$

$$
\frac{65}{64}d^2 = 10000
$$

Now, solving for $$ d^2 $$:

$$
d^2 = 10000 \cdot \frac{64}{65}
$$

Now, let's calculate $$ d^2 $$ and then find $$ h $$.

### Step 3: Calculate $$ h $$

After finding $$ d $$, we can calculate $$ h $$ using the relationship $$ h = \frac{1}{8} \cdot d $$.

### Step 4: Calculate the Angle of Elevation

The angle of elevation can be calculated using the tangent function:

$$
\tan(\theta) = \frac{h}{d}
$$

Thus,

$$
\theta = \tan^{-1}\left(\frac{h}{d}\right)
$$

Now, let's perform the calculations.

  $$10000\times \frac{64}{65}$$

- step3: Reduce the numbers:
  $$1\times \frac{20\sqrt{65}}{13}$$
- step4: Multiply:
  $$\frac{20\sqrt{65}}{13}$$
Calculate or simplify the expression $$ \arctan(12.403473 / 99.227788) $$.
Calculate the value by following steps:
- step0: Calculate:
  $$\arctan\left(\frac{12.403473}{99.227788}\right)$$
