Question

If one leg of a right triangle is 4 and the hypotenuse is 5, find the missing leg

Answer 1

According to Pythagorean theorem

a² = b² + c² where a is hypotenuse , b and c are legs of the right triangle

5² = 4² + x²

25 = 16 + x²

25 - 16 = x²

9 = x²

√9 = √x²

3 = x

so the other leg is equal to 3
