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.
