Ladder Height
1. **State the problem:** Kali has a 6 meter ladder leaning against a tree. The base of the ladder is 2 meters from the tree. We need to find how high the ladder reaches on the tree.
2. **Identify the triangle sides:** The ladder is the hypotenuse $c = 6$ meters.
The base (distance from tree to ladder base) is $b = 2$ meters.
The height $h$ (how high the ladder reaches) is unknown.
3. **Apply the Pythagorean theorem:** For a right triangle,
$$h^2 + b^2 = c^2$$
Substitute known values:
$$h^2 + 2^2 = 6^2$$
$$h^2 + 4 = 36$$
4. **Solve for $h^2$:**
$$h^2 = 36 - 4 = 32$$
5. **Find $h$ by taking the square root:**
$$h = \sqrt{32} = \sqrt{16 \times 2} = 4\sqrt{2} \approx 5.656854$$
6. **Round to the nearest tenth:**
$$h \approx 5.7$$ meters
**Final answer:** The ladder reaches approximately 5.7 meters high into the tree.
