If AC = 15 centimeters, and BC = 12 centimeters, which does AB equal?

To find the length of AB, we need to use the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the other two sides.

In this case, AC and BC form a right triangle, and AB is the hypotenuse. So we have:

AB^2 = AC^2 + BC^2

Plugging in the given lengths:

AB^2 = 15^2 + 12^2

AB^2 = 225 + 144

AB^2 = 369

To determine the value of AB, we need to take the square root of both sides:

AB = √369

Using a calculator or an approximation, we find that the square root of 369 is approximately 19.21 centimeters. Therefore, AB is approximately 19.21 centimeters.

15 - 12 = ?

If AC = 20 centimeters, and BC = 16 centimeters, which does AB equal?
