The image shows a right-angled triangle $\triangle ZPT$, where:

• $PZ$ is the vertical leg, labeled as 4.
• $ZT$ is the hypotenuse, labeled as X.
• $PT$ is the horizontal leg.

Would you like me to find $X$ or any other specific value? Let me know how you'd like to proceed!

Here are five related questions to expand on this topic:

1. How do we use the Pythagorean theorem to find the hypotenuse?
2. If we know $PT$, how do we verify the triangle using the theorem?
3. What is the sine, cosine, or tangent of one of the angles?
4. How do we determine the area of the triangle?
5. Can we apply trigonometry to solve for missing sides?

Tip:

For any right-angled triangle, the Pythagorean theorem states:
$a^2 + b^2 = c^2$
where $c$ is the hypotenuse.
