What is the tan(x) for each triangle

**Question 11**

**What is the tan(x) for each triangle?** * [2 points]

The image shows two right-angled triangles.

**Triangle on the left:**
- Angle \(X\)
- Side \(A\) (adjacent to angle \(X\))
- Side \(B\) (opposite to angle \(X\))
- Hypotenuse \(C\)
- Right angle (\(90^\circ\))

**Triangle on the right:**
- Angle \(X\)
- Side \(D\) (adjacent to angle \(X\))
- Side \(E\) (opposite to angle \(X\))
- Hypotenuse \(F\)
- Right angle (\(90^\circ\))

**Explanation of `tan(x)`:**
The tangent of an angle in a right triangle is the ratio of the length of the opposite side to the length of the adjacent side.

\[ \tan(X) = \frac{\text{opposite side}}{\text{adjacent side}} \]

For the triangle on the left:
\[ \tan(X) = \frac{B}{A} \]

For the triangle on the right:
\[ \tan(X) = \frac{E}{D} \]

To find the exact values of \( \tan(X) \) for each triangle, substitute the lengths of the sides into the respective formulas.
