Let's solve both problems one by one.

### Problem 11: Height of Micah's School
This problem involves similar triangles. From the diagram, you can see that there are two right triangles: 
- One triangle for Micah, the mirror, and the school.
- Another smaller triangle with known dimensions for the mirror setup.

We are given:
- Micah is standing 93.5 feet from the school.
- The distance between Micah and the mirror is 12.75 feet.
- The height of Micah is 6 feet.

Since these triangles are similar, the ratios of the corresponding sides should be equal. This gives us the equation:

\[
\frac{\text{Height of the school } (x)}{93.5} = \frac{6}{12.75}
\]

Now, let's solve for \( x \) (the height of the school).

\[
x = \frac{6}{12.75} \times 93.5
\]

### Problem 12: Distance from the Parking Lot to the Clearing
This problem requires applying the **Law of Cosines** since we have a non-right triangle formed by the points: parking lot, flagpole, and clearing.

We are given:
- Distance from the flagpole to the forest ranger station: 154 feet.
- Distance from the flagpole to the clearing: 350 feet.
- The angle between these sides (since the diagram doesn't provide it explicitly, we may assume it's a typical case of application, perhaps 90°, or the full problem might clarify more).

Let's calculate these values step by step, using the Law of Cosines if needed. First, I'll calculate the height of Micah's school, then proceed to the second part.

Let me solve this.### Solution to Problem 11:
The height of Micah's school is **44 feet**.

Now let's move on to solving **Problem 12**. The problem appears to involve using the Law of Cosines to find the distance from the parking lot to the clearing.

Since the exact angle between the sides of 154 feet and 350 feet is not provided in the problem, could you confirm whether this angle is 90°, or if any additional information is given in the full problem statement? This would allow me to calculate the distance more accurately.

Let me know if you'd like further explanation for the first part! Here's a quick set of related questions for you:

1. How does the concept of similar triangles help in practical geometry?
2. Could this method be applied to other everyday scenarios, like estimating the height of a tree or a building?
3. How would you calculate the angle if you had additional information for Problem 12?
4. How does the Law of Cosines differ from the Pythagorean Theorem in triangle problems?
5. What additional measurements could you take to double-check your solution in Problem 11?

**Tip:** In geometry, similar triangles are powerful tools for scaling measurements when direct calculation is hard or impossible!

Problem 11: Micah wants to know the height of his school. He places a small mirror on the ground between himself and the school, then backs up until he can see the highest point of the school in the mirror. What is the height of Micah's school?
Problem 12: Marsha wants to walk from the parking lot through the forest to the clearing. She knows that the forest ranger station is 154 feet from the flag pole and the flag pole is 350 feet from the clearing. How far is the parking lot from the clearing?

Learn how to solve real-world geometry problems using similar triangles and the Law of Cosines. Problem 11 explores calculating the height of a school using mirrors and geometric ratios, while Problem 12 applies the Law of Cosines to find the distance between a parking lot and clearing through a forest.
