A right triangles hypotenuse has length 5. if one leg has length 2, what is the length of the other leg

To solve this question, we would make use of the Pythagorean theorem to solve for the missing side. Since it is a right angle triangle we are able to do this.

A^2 + B^2 = C^2

A^2 = C^2 - B^2

A^2 = (5) ^2 - (2) ^2

A^2 = 25 - 4

A^2 = 21

A = ✔️21.

The length of the other leg for this right triangle would be ✔️21.
