This is a right triangle where two sides are labeled: one side is 10 cm, the other is 6.5 cm, and the angle between them is a right angle (90°).

To find the missing side $a$ (the hypotenuse), we can use the Pythagorean theorem, which states:

$a^2 = 6.5^2 + 10^2$

Now, let’s calculate $a$. math

Given values

side1 = 6.5 # cm side2 = 10 # cm

Pythagorean theorem to calculate the hypotenuse (a)

a = math.sqrt(side12 + side22) aThe length of the hypotenuse $a$ is approximately 11.93 cm.
