Question

A right triangle has a hypotenuse of length 13 in. and a leg with length 4 in. What is the length of the other leg?

Answer 1

Solution,

Let the hypotenuse of the right triangle be 'a' and its legs be 'b' and 'c'.

Here, a= 13, b = 4 and c=?

Using Pythagoras or Gogou theorem,

a² = b² +c²

or, 13² = 4² +c²

or, c² =153

or, c = 3√17 inch
