Question

please answer the problem below

Answer 1

Answer:

21 is the correct answer

Answer 2

Let the unknown side be "x"

By using Pythagorean Theorem, we can find the length of the missing side.

We know that, in a right triangle:-

Base² + Altitude² = Hypotenuse²

Similarly, in the given triangle:--

-> x² + 72² = 75²

-> x² + 5184 = 5625

-> x² = 441

-> x = √441

-> x = 21

∴ The missing side is 21 cm
