To find the length of $YZ$, we can assume this is a triangle problem, likely involving a right triangle where the given angles and side lengths relate to trigonometric principles. Here's how to approach it:

Assumptions:

1. The diagram consists of a triangle with known angles and side lengths.
2. Two angles are $40^\circ$.
3. The side opposite one of the $40^\circ$ angles is labeled $W$ and is $29$.
4. The triangle's configuration suggests a relationship between these values to find $YZ$.

Solution:

Let's use trigonometric functions based on the given information. If the side $W = 29$ is adjacent to one of the $40^\circ$ angles, and we want to find the length $YZ$, we can use the tangent function:

$\tan(40^\circ) = \frac{\text{opposite}}{\text{adjacent}}$

However, since the specifics of $W$'s placement relative to $YZ$ aren't entirely clear, there might be different cases (opposite, adjacent, or hypotenuse). Here's the generic approach to solving:

1. Using Tangent: If $W$ is adjacent, then:

   $YZ = W \times \tan(40^\circ) = 29 \times \tan(40^\circ)$

2. Calculations: $YZ \approx 29 \times 0.8391 \approx 24.33$

Final Answer:

$YZ \approx 24.33$

Always identify the correct trigonometric ratio based on the known and unknown sides relative to the given angle.
