Question

If one leg of a triangle is 13 centimeters long and the other leg is 15 centimeters long then what is the length of the hypotenuse

Answer 1

`a^(2) +b^(2) =c^(2) 13^(2) +15 ^(2) =C^(2) 169+225=C ^(2) C^(2) =√(389) = 19.72`

Answer 2

By the Pythagorean Theorem:

h^2=x^2+y^2

h^2=169+225

h^2=394

h=√394 cm

h≈19.85 cm (to nearest one-hundredth of a cm)
