Given a right triangle with:
Side length = 3 and Hypotenuse = 5
Calculate the remaining side:
Pythagorean Theorem Formula
Side12 + Side22 = Hypotenuse2
Solve for Side 2
Take the square root of both sides
Side 2 = √Hypotenuse2 - Side 12
Plug in Hypotenuse = 5 and Side 1 = 3
Side 2 = √52 - 32
Side 2 = √25 - 9
Side 2 = √16
Final Answer
Side 2 = 4
