By applying Pythagorean's theorem to the right-angled triangles, the values of x, y, z include;
x = 11.2 cm.
y = 17.16 cm.
z = 25.76 cm.
In Mathematics and Geometry, Pythagorean theorem is an Euclidean postulate that can be modeled or represented by the following mathematical equation:

Where:
- a is the opposite side of a right-angled triangle.
- b is the adjacent side of a right-angled triangle.
- c is the hypotenuse of a right-angled triangle.
In order to determine the length of h, we would have to apply Pythagorean's theorem as follows;

x = 11.2 cm.
For the value of y, we have:

y = 17.16 cm.
For the value of z, we have:

z = 25.76 cm.
