Question

What is the length of the hypotenuse of a right triangle if the two other sides are of lengths 3 and 16?

Answer 1

`sqrt265`

Explanation:

Pythagoras Theorem states that in a right angled triangle, the square of the hypotenuse is equal to the sum of the squares of the other 2 sides.
ie. `r^2=x^2+y^2`.

`therefore r=sqrt(x^2+y^2)`

`=sqrt(3^2+16^2)`

`=sqrt265`.
